- device 16 comprises a small sponge or swab located on or near connector 104 to collect any fuel leakage during device connection or disconnect.
- one of connector 104 and mating connector 140 includes a ‘male’ designation and configuration while the other includes a ‘female’ designation and configuration.
- the male configuration includes portions of the connector that protrude, such as one or more pins or electrical leads.
- the female configuration includes portions of the connector that receive the male portions, such as holes electrically lined to receive the male portion and facilitate electrical communication.
- connector 104 on storage device 16 includes a female configuration that recesses within housing 102 . Since it is recessed, connector 104 cannot be knocked off during rough handling.
- Mating connector 140 is configured on a side portion of an OEM device (i.e., a laptop computer). As will be described in further detail below, mating connector 140 is also included in refilling hardware that refills storage device 16 with fuel source 17 .

- Writing to a digital memory 106 allows information in memory 106 to be updated according to storage device 16 usage. Thus, if a user nearly depletes fuel source 17 in storage device 16 while powering a computer, the next user may be informed after the first computer writes an updated amount of fuel source 17 remaining in storage device 16 into memory 106 .
- Storage device 16 specifications stored in memory 106 generally do not change with device 16 usage and may comprise a) a fuel type stored in the storage device when device 16 is dedicated to service a particular hydrocarbon fuel source 17 , b) a model number for storage device 16 , c) an identification signature for the manufacturer of storage device 16 , d) manufacture date, and e) a volume capacity for bladder 100 or storage device 16 .
- the model number of device 16 allows it to be distinguished from a number of similar devices.

- storage device 16 resembles a battery-sized cartridge including a female connector 104 that receives a male mating connector 140 .
- Male housing 113 of mating connector 140 fits snugly into a female bay 117 of connector 104 (see FIG. 2G for side view of a bay 117 ). The fit provides mechanical support for the interface between mating connector 140 and connector 104 .
- Distal end of tube 107 in storage device 16 and a distal end of tube 109 in mating connector 140 align when connector 104 and mating connector 140 join.
- tube 109 comprises a pointed end that pierces into tube 107 and tube 109 comprises a diameter that snugly fits into tube 107 when connector 104 and mating connector 140 are attached.
- a pump run by a fuel cell system 10 within laptop computer 202 draws fluid from bladder 100 into the fuel cell system 10 . More specifically, fuel source 17 travels from bladder 100 , through tube 107 in connector 104 , into and through tube 109 in mating connector 140 , and through tube 109 in laptop computer 202 to a fuel processor 15 included therein.
- Connector 104 and mating connector 140 may also include electrical connectivity for digital communication between memory 106 and a processor or controller (see FIG. 4 ) on laptop computer 202 .
- FIG. 2F illustrates female electrical slots 155 on connector 104 b .
- a mating connector 140 for connector 104 b then includes male leads (not shown) that fit into slots 155 for electrical communication between laptop computer 202 and storage device 16 .
- bladder 100 comprises a collapsible bellows design 126 .
- One end 127 a of bellows 126 attaches and opens to tube 107 , while the opposite end 127 b is free to move in direction 125 .
- free end 127 b moves in direction 125 and bellows 126 expands and increases in volume.
- free end 127 b and bladder 100 thus compresses towards the location where fuel source 17 is outlet and where negative pressure is created to contract or collapse bellows 126 (tube 107 and connector 104 in this case).
- FIG. 2C illustrates a bellows configuration 126 at its maximum volume.
- bladder 100 is less than half full of fuel source 17 and assumes less than half the space in internal cavity 112 .
- Bellows 126 comprises collapsible rings 128 that fold as bellows 126 expands (the angle of each ring 128 opens) and as bellows 126 collapse (the angle of each ring 128 closes).
- Bellows 126 may comprise plastic or Nickel, for example.
- Bellows 126 may be custom molded or electroformed. Similarly designed bellows are used to protect tubular warp in machine tools, for example.
- Servometer Corp. of New Jersey provides several suitable commercially available nickel bellows.
- Storage device 16 includes an air vent 132 in housing 102 that allows air to enter and exit in internal cavity 112 within housing 102 as bladder 100 changes in volume.
- Air vent 132 comprises one or more holes or apertures in a wall 110 of housing 102 .
- bladder 100 collapses and creates a negative pressure in internal cavity 112 outside of bladder 100 . Based on this negative pressure caused by a decreasing volume of bladder 100 (or increasing volume of internal cavity 112 outside bladder 100 ), air enters through air vent 132 into internal cavity 112 and displaces the decreasing volume of bladder 100 . This prevents the pressure of fuel source 17 in bladder 100 from decreasing and affecting the ability of storage device 16 to provide fuel source 17 at a substantially constant pressure.
- bladder 100 When filling storage device 16 , positive pressure caused by an increasing volume of fuel source 17 and bladder 100 causes air to exit through air vent 132 . Since walls of bladder 100 separate fuel source 17 within bladder 100 from air in internal cavity 112 , air in cavity 112 does not enter bladder 100 or mix with fuel source 17 .
- a filter 134 spans the cross section of air vent 132 and intercepts air passing through air vent 132 .
- filter 134 comprises a hydrophobic and gas permeable filter that prevents foreign materials from entering storage device 16 .
- Materials blocked by filter 134 may include liquids and particles such as undesirable oils and abrasives that may affect storage device 16 performance.
- the hydrophobic filter also prevents fuel source 17 from escaping housing 102 in the event that bladder 100 develops a leak.
- Filter 134 may comprise micro porous Teflon or another micro porous material such as Teflon coated paper.
- a sintered metal filter for example one with a 3 micron pore size, may also be used.
- One suitable filter 134 includes micro porous “Gore Tex” Teflon as provided by WL Gore Associates of Elkton, Md.
- Mechanical shield 142 spans and covers air vent 132 and prevents foreign bodies from entering housing 102 through air vent 132 and damaging bladder 100 .
- air vent 132 is recessed into a wall 110 such that mechanical shield 142 is flush with the outer surface of housing 102 .
- filter 134 is located internal to shield 142 such that shield 142 mechanically protects filter 134 .
- mechanical shield 142 includes a flame suppressor or a suitable means of flame suppression. The mechanical shield 142 then prevents flame propagation into or out from interior cavity 112 .
- One suitable mechanical shield 142 includes cut to size 180 ⁇ 180 mesh stainless steel screen as provided by McNichols of Tampa, Fla.
- Pressure relief valve 136 limits pressure in storage device 16 . More specifically, pressure relief valve 136 releases fuel source 17 from bladder 100 when the pressure within bladder 100 reaches a threshold pressure.
- the threshold pressure refers to a pressure for bladder 100 that represents the upper limit of operational pressure for fuel source 17 use in storage device 16 . Threshold pressures from about 5 psig to about 25 psig are suitable for some fuel sources 17 and storage devices 16 . A threshold pressure of about 15 psig is suitable in many cases. Other suitable threshold pressures may relate to the boiling point of the fuel source 17 , which ranges from about 2 Atm to about 10 Atm. Thus, if temperature for storage device 16 rises above the boiling point of fuel source 17 , the threshold pressure is reached and pressure relief valve 136 releases fuel source 17 from bladder 100 .
- the partial pressure of fuel source 17 in bladder 100 is less than the threshold pressure and pressure relief valve 136 is not used. In the event that pressure of fuel source 17 in bladder 100 rises above the threshold pressure, pressure relief valve 136 releases fuel source 17 from bladder 100 , thereby limiting the pressure within bladder 100 .
- pressure relief valve 136 comprises a sprung diaphragm mechanism.
- the sprung diaphragm includes a diaphragm and a spring that attaches to the diaphragm. Pressure in bladder 100 pushes the diaphragm outward against the spring force. At the threshold pressure, the diaphragm opens a port—a small hole that opens outside of housing 102 —to permit the release of fuel source 17 from bladder 100 . Spring selection permits a designer to control the threshold pressure at which the port opens and fuel source 17 escapes.
- pressure relief valve 136 comprises a burst disk mechanism that includes a thin diaphragm. The diaphragm breaks outward when pressure in bladder 100 rises above the threshold pressure. The diaphragm break and the resultant opening releases fuel source 17 from bladder 100 .
- the port or opening may be configured to direct venting fuel vapors away from storage device 16 and into a ventilated area when installed in an electronics or OEM device.
- a fuel source filter 144 intercepts fuel source 17 as it leaves bladder 100 and before it leaves connector 104 . As shown, filter 144 spans an entrance to tube 107 from bladder 100 .

- fuel source 17 comprises an odorant 150 , a bitterant 152 and/or a colorant 154 mixed therein. If fuel source 17 comprises an odorless liquid, odorant 150 provides olfactory stimulus to inform a person that fuel source 17 has escaped bladder 100 and storage device 16 via a path other than through tube 107 and filter 144 .
- Two suitable odorants 150 includes trimethyl amine at 1-10 ppm in methanol and ethyl mercaptan at 1-7 ppm weight in methanol.
- Fuel source filter 144 removes odorant 150 from fuel source 17 when the fuel source leaves bladder 100 through tube 107 .
- colorant 154 provides visual stimulus to inform a person that fuel source 17 has leaked or escaped from bladder 100 via a path other than through tube 107 and filter 144 .
- Suitable colorants 154 include acid blue 9 at 1 ppm, table 5-4 food dye, and bright green/blue erioglaicine disodium salt as provided by Dudley Chemical Corp of Lakewood, N.J.
- Fuel source filter 144 removes colorant 154 from hydrogen fuel source 17 when the fuel source leaves bladder 100 through tube 107 .
- a bitterant 152 may be added to provide taste stimulus that informs a person that fuel source 17 has escaped bladder 100 via a path other than through tube 107 and filter 144 .
- One suitable bitterant 152 includes Denatonium Benzoate at 1-50 ppm (20-50 ppm is adversely bitter) as provided by Bitrex of Edinburgh, UK.
- Fuel source filter 144 removes bitterant 152 from hydrogen fuel source 17 when fuel source 17 leaves bladder 100 through tube 107 .
- One suitable filter 144 for removing odorant 150 , bitterant 152 and/or colorant 154 includes an ultra-pure polyethersulfone membrane.
- Another suitable filter 144 for removing odorant 150 , bitterant 152 and/or colorant 154 from fuel source 17 includes 0.1 Advantage PS C-7012 filter as provided by Parker Hanafin Corp.
- a fire retardant foam 138 is disposed in bladder 100 .
- Foam 138 is compliant and conforms in size to the size of bladder 100 . Thus, as bladder 100 collapses, foam 138 compresses. In one embodiment, foam 138 acts as a wicking foam that directs some flame behavior in storage device 16 .
- One suitable foam 138 is polyurethane mil Spec Mil-B-83054 as provided by Foamex of Lindwood, Pa.

- the interrogator may include any hardware for performing this function such as a computer, transceiver and interrogator antenna. Coupling between the interrogator and storage device 16 may occur via radio frequency (RF) or microwave frequency radiation.
- RF radio frequency
- storage device 16 When probed by the interrogator, storage device 16 replies with its identification (as stored in a digital or electrical memory 106 ) and any other information stored in memory 106 , such as the status of any sensors used in storage device 16 to monitor health of the device and sensors that detect the volume of fuel source in bladder 100 .
- the storage device 16 identification provides a means for automated logging of data corresponding to the status of storage device 16 .
- the identification also facilitates inventory logging of information for numerous storage devices 16 .
- the interrogator provides power to storage device 16 .
- the power is transmitted by RF waves, for example, and received by a rectifier in storage device 16 that rectifies the signal, thereby providing sufficient DC power to operate any circuitry of storage device 16 .
- a transponder included in storage device 16 responds to a wireless stimulus.
- the transponder transmits signals when actuated by a signal from an external interrogator.
- the transponder includes an amplifier for increasing the strength of a received incident signal, a modulator for modifying the signal with information stored by memory 106 , and an antenna or antennas for receiving and transmitting signals.

- Storage device 16 may also comprise a sensor that monitors a condition related to the health or functioning of storage device 16 .
- the sensor comprises a wire 156 that runs about an inside surface of housing 102 or is formed within a wall 110 housing 102 (see FIG. 2C ).
- An electrical state or performance of wire 156 provides an indication of the health of housing 102 .
- Mechanical damage, cracking or structural compromise of housing 102 affects wire 156 —mechanically and electrically. More specifically, when wire 156 breaks, stretches or loses contact due to mechanical changes housing 102 , an electrical signal sent through wire 156 changes. The according change may be read and assessed. Thus, a break in wire 156 may be read by non-transmittance of a signal.
- Changes in electrical resistance of wire 156 may also provide an indication of health.
- the sensor relies on external (e.g., RFID) probing to assess the state of wire 156 and health of housing 102 .
- the interrogator powers memory 106 to test the resistance of wire 156 .
- the RFID memory 106 then responds with a signal indicative of the status of wire 156 .
- the sensor is shown as a single wire 156 , it is understood that more complex designs may comprise filament networks that extend two dimensionally throughout housing 102 . Each filament may then be probed for its electrical status, e.g., resistance to provide a meshed status check of integrity and health of housing 102 and storage device 16 .

- Connector 104 and/or mating connector 140 may include a ‘keyed’ configuration that provides interface selectivity.
- connector 104 may comprise a configuration unique to a particular hydrogen fuel source (e.g., methanol).
- mating connector 140 offers an exclusive interface that only receives a connector 104 for a methanol based storage device 16 .
- This keying system prevents the wrong fuel type from being installed in a device that cannot accept that fuel, e.g., gasoline burns at a higher temperature and may not be suitable for use in all methanol fuel processors.
- This keying system also prevents storage device 16 from being refilled with the wrong hydrogen fuel source 17 .

- storage device 16 b of FIG. 2E includes a circular connector 104 a of the same dimensions that interfaces with the same circular mating connector as that employed for connector 104 a .
- the storage device 16 c of FIG. 2F includes a rectangular connector 104 b that would not interface with the same circular mating connector.
- Circular connectors 104 a may be used for methanol fuel mixtures of different blends for example, while rectangular connector 104 b is used for ethanol.
- connector 104 may change slightly while mating connector 140 remains constant.
- a common mating connector 140 may receive different storage devices 16 that share a connector 104 a configuration.
- the different storage devices 16 may be produced by different manufacturers and may include varying volumes or other storage device 16 features. This permits competition for the provision of storage devices 16 but standardization of their interface.
- an electronics device manufacturer such as Dell specifies a custom mating connector 140 configuration (e.g., a circular configuration used in their laptop computers and other electronics devices). All storage devices 16 that service these electronics devices must then include a connector 104 that matches Dell's custom mating connector 140 configuration.
- the electronics device manufacturer may then control who manufacturers storage devices 16 and connectors 104 for use with their electronics devices. Keyed connectors 104 a for one electronics device manufacturer may also be designed to not fit a mating connector 140 for another computer manufacturer, e.g., Apple employs a rectangular configuration 104 b.
- Custom connector 104 and mating connector 140 configurations may vary based on geometry, dimensions, depth and size for example.

- Spent storage devices 16 may be dropped off at the any of the above locations for reuse, and shipped to a refilling services provider for refurbishment and refill.
- refiller 162 may also rejuvenate or check for replacement of the cleaning system.
- refiller 162 rejuvenates the cleaning system by forcing hydrogen through the bed (e.g., using hydrogen in tank 164 ).
- the scrubbing bed filter 220 may also be replaced with a new bed when the storage device 16 is refilled.
- Refilling system 160 allows a hydrogen fuel source 17 refilling provider to control refilling of storage devices 16 .
- Connectors 104 that require specific parts on mating connector 140 to complete interface and permit fluid transfer into storage device 16 also prevent free tampering and addition of fluids to storage device 16 .

FIG. 1A illustrates afuel cell system 10 for producing electrical energy in accordance with one embodiment of the present invention.Fuel cell system 10 comprisesstorage device 16,fuel processor 15 andfuel cell 20. -
Storage device 16 andfuel processor 15 provide hydrogen tofuel cell 20.Storage device 16 andfuel processor 15 collectively act as a ‘reformed’ hydrogen supply that processes ahydrogen fuel source 17 to produce hydrogen.Hydrogen fuel source 17 acts as a carrier for hydrogen and can be processed to separate hydrogen.Hydrogen fuel source 17 may include any hydrogen bearing fuel stream, aliphatic fuel source or other hydrogen carrier such as ammonia. Currently availablehydrocarbon fuel sources 17 suitable for use with the present invention include methanol, ethanol, gasoline, propane, butane and natural gas, for example. Several hydrocarbon and ammonia products may also produce asuitable fuel source 17.Liquid fuel sources 17 offer high energy densities and the ability to be readily stored and shipped. -
Storage device 16 stores fuelsource 17, and may comprise a refillable and/or disposable fuel cartridge. A refillable cartridge offers a user instant recharging. In one embodiment, the cartridge includes a collapsible bladder within a hard plastic case.Storage device 16 is portable and described in further detail below. - A separate fuel pump typically controls
fuel source 17 flow fromstorage device 16. Ifsystem 10 is load following, then a control systemmeters fuel source 17 to deliverfuel source 17 toprocessor 15 at a flow rate determined by the required power level output offuel cell 20. -
Fuel processor 15 processes thehydrocarbon fuel source 17 and outputs hydrogen. Ahydrocarbon fuel processor 15 heats and processes ahydrocarbon fuel source 17 in the presence of a catalyst to produce hydrogen.Fuel processor 15 comprises a reformer, which is a catalytic device that converts a liquid or gaseoushydrocarbon fuel source 17 into hydrogen and carbon dioxide. As the term is used herein, reforming refers to the process of producing hydrogen from a fuel source. -
Fuel cell 20 electrochemically converts hydrogen and oxygen to water, generating electrical energy and heat in the process. Ambient air commonly supplies oxygen forfuel cell 20. A pure or direct oxygen source may also be used for oxygen supply. The water often forms as a vapor, depending on the temperature offuel cell 20 components. The electrochemical reaction also produces carbon dioxide as a byproduct for many fuel cells. - In one embodiment,
fuel cell 20 is a low volume polymer electrolyte membrane (PEM) fuel cell suitable for use with portable applications such as consumer electronics. A polymer electrolyte membrane fuel cell comprises amembrane electrode assembly 40 that carries out the electrical energy generating electrochemical reaction. Themembrane electrode assembly 40 includes a hydrogen catalyst, an oxygen catalyst and an ion conductive membrane that a) selectively conducts protons and b) electrically isolates the hydrogen catalyst from the oxygen catalyst. A hydrogen gas distribution layer contains the hydrogen catalyst and allows the diffusion of hydrogen therethrough. An oxygen gas distribution layer contains the oxygen catalyst and allows the diffusion of oxygen and hydrogen protons therethrough. The ion conductive membrane separates the hydrogen and oxygen gas distribution layers. In chemical terms, the anode comprises the hydrogen gas distribution layer and hydrogen catalyst, while the cathode comprises the oxygen gas distribution layer and oxygen catalyst. - A PEM fuel cell often includes a fuel cell stack having a set of bi-polar plates. A membrane electrode assembly is disposed between two bi-polar plates.
Hydrogen distribution 43 occurs via a channel field on one plate whileoxygen distribution 45 occurs via a channel field on a second facing plate. Specifically, a first channel field distributes hydrogen to the hydrogen gas distribution layer, while a second channel field distributes oxygen to the oxygen gas distribution layer. The ‘term ‘bi-polar’ refers electrically to a bi-polar plate (whether comprised of one plate or two plates) sandwiched between two membrane electrode assembly layers. In this case, the bi-polar plate acts as both a negative terminal for one adjacent membrane electrode assembly and a positive terminal for a second adjacent membrane electrode assembly arranged on the opposite face of the bi-polar plate. - In electrical terms, the anode includes the hydrogen gas distribution layer, hydrogen catalyst and bi-polar plate. The anode acts as the negative electrode for
fuel cell 20 and conducts electrons that are freed from hydrogen molecules so that they can be used externally, e.g., to power an external circuit. In a fuel cell stack, the bi-polar plates are connected in series to add the potential gained in each layer of the stack. In electrical terms, the cathode includes the oxygen gas distribution layer, oxygen catalyst and bi-polar plate. The cathode represents the positive electrode forfuel cell 20 and conducts the electrons back from the external electrical circuit to the oxygen catalyst, where they can recombine with hydrogen ions and oxygen to form water. - The hydrogen catalyst separates the hydrogen into protons and electrons. The ion conductive membrane blocks the electrons, and electrically isolates the chemical anode (hydrogen gas distribution layer and hydrogen catalyst) from the chemical cathode. The ion conductive membrane also selectively conducts positively charged ions. Electrically, the anode conducts electrons to a load (electrical energy is produced) or battery (energy is stored). Meanwhile, protons move through the ion conductive membrane. The protons and used electrons subsequently meet on the cathode side, and combine with oxygen to form water. The oxygen catalyst in the oxygen gas distribution layer facilitates this reaction. One common oxygen catalyst comprises platinum powder very thinly coated onto a carbon paper or cloth. Many designs employ a rough and porous catalyst to increase surface area of the platinum exposed to the hydrogen and oxygen.
- In one embodiment,
fuel cell 20 comprises a set of bi-polar plates formed from a single plate. Each plate includes channel fields on opposite faces of the plate. Since the electrical generation process infuel cell 20 is exothermic,fuel cell 20 may implement a thermal management system to dissipate heat from the fuel cell. Further description of a fuel cell suitable for use with the present invention is included in commonly owned co-pending patent application entitled “Micro Fuel Cell Architecture” naming Ian Kaye as inventor and filed on Jun. 25, 2004, which is incorporated by reference for all purposes. - While the present invention will mainly be discussed with respect to PEM fuel cells, it is understood that the present invention may be practiced with other fuel cell architectures. The main difference between fuel cell architectures is the type of ion conductive membrane used. In one embodiment,
fuel cell 20 is phosphoric acid fuel cell that employs liquid phosphoric acid for ion exchange. Solid oxide fuel cells employ a hard, non-porous ceramic compound for ion exchange and may be suitable for use with the present invention. Generally, any fuel cell architecture may benefit from the fuel storage improvements described herein. Other such fuel cell architectures include direct methanol, alkaline and molten carbonate fuel cells. -
Fuel cell 20 generates dc voltage that may be used in a wide variety of applications. For example, electrical energy generated byfuel cell 20 may be used to power a motor or light. In one embodiment, the present invention provides ‘small’ fuel cells that are configured to output less than 200 watts of power (net or total). Fuel cells of this size are commonly referred to as ‘micro fuel cells’ and are well suited for use with portable electronics devices. In one embodiment,fuel cell 20 is configured to generate from about 1 milliwatt to about 200 watts. In another embodiment,fuel cell 20 generates from about 3 W to about 20W. Fuel cell 20 may also be a stand-alone fuel cell, which is a single unit that produces power as long as it has an a) oxygen and b) hydrogen or a hydrocarbon fuel supply. A stand-alone fuel cell 20 that outputs from about 40 W to about 100 W is well suited for use in a laptop computer. - In one embodiment,
fuel processor 15 is a steam reformer that only needs steam and thefuel source 17 to produce hydrogen. Several types of reformers suitable for use infuel cell system 10 include steam reformers, auto thermal reformers (ATR) or catalytic partial oxidizers (CPOX). ATR and CPOX reformers mix air with the fuel and steam mix. ATR and CPOX systems reform fuels such as methanol, diesel, regular unleaded gasoline and other hydrocarbons. In a specific embodiment,storage device 16 providesmethanol 17 tofuel processor 15, which reforms the methanol at about 250° C. or less and allowsfuel cell system 10 use in applications where temperature is to be minimized. Further description of a fuel processor suitable for use with the present invention is included in commonly owned co-pending patent application entitled “Efficient Micro Fuel Cell Systems and Methods” naming Ian Kaye as inventor and filed on Jun. 25, 2004, which is incorporated by reference for all purposes. -

dewar 36 that pre-heats air before the air entersburner 30. The dewar also reduces heat loss fromfuel cell 20 by heating the incoming air before it escapesfuel processor 15. In one sense, dewar acts as a regenerator that uses waist heat infuel processor 15 to increase thermal management and thermal efficiency of the fuel processor. Specifically, waist heat fromburner 30 may be used to pre-heat incoming air provided toburner 30 to reduce heat transfer to the air in the burner so more heat transfers toreformer 32. -

In some cases,storage device 16 comprisesmultiple bladders 100 that each contributes a maximum volume that cumulatively add to a total fuel source capacity forstorage device 16. For example, aspare storage device 16 intended for electronics power back-up may contain twobladders 100 each including 300 milliliters ofhydrogen fuel source 17. - While the present invention primarily refers to the storage of methanol in
bladder 100 andstorage device 16, it is understood thatbladder 100 andstorage device 16 may contain other hydrocarbon fuel sources such as those listed above. In addition,bladder 100 may contain a fuel mixture. For example, when thefuel processor 15 fed bystorage device 16 comprises a steam reformer,bladder 100 may contain a fuel mixture of a hydrocarbon fuel source and water. Hydrocarbon fuel source/water fuel mixtures are often represented as a percentage fuel source in water. In one embodiment,hydrogen fuel source 17 comprises methanol or ethanol concentrations in water in the range of 1%-99.9%. Alternatively,hydrogen fuel source 17 may comprise 100% methanol or ethanol. Other liquid fuels such as butane, propane, gasoline, military grade “JP8” etc. may also be contained instorage device 16 with concentrations in water from 5-100%. In a specific embodiment,bladder 100 stores 67% methanol by volume. -
Housing 102 provides mechanical protection forbladder 100 and any other components ofstorage device 16 included withinhousing 102.Housing 102 comprises a set ofrigid walls 110 that containbladder 100 and other internal components ofstorage device 16. In one embodiment, all components ofstorage device 16 are contained withinhousing 102 save any portions ofconnector 104 that protrude out of the housing for interface withmating connector 140. In another embodiment,connector 104 is recessed withinhousing 102 andhousing 102 provides an outer shell that substantially defines outer bounds and shape ofstorage device 16.Walls 110 collectively form an outer case or shell forstorage device 16 that mechanically separates components internal tohousing 102 from the external environment.Walls 110 also collectively form aninterior cavity 112.Interior cavity 112 is a space within storage device that containsbladder 100. As described below,interior cavity 112 may comprises multiple compartments, each of which include aseparate bladder 100. -
Rigid walls 110 may comprise a suitably stiff material such as a plastic, metal (e.g., aluminum), polycarbonate, polypropelene, carbon fiber matrix, carbon composite material, etc.Rigid walls 110 may also be formed from a fire retardant material such as a fire retardant plastic material. One suitable fire retardant plastic material forwalls 110 is 8-12% weight, JLS-MC mixed with PA66 Polyamide as provided by JLS Chemical of Pomona, Calif.Rigid walls 110 may be designed according to criteria for construction of thin walled pressure vessels. Such criteria are known to those of skill in the art. In this case,walls 110 andhousing 102 may be designed to withstand a maximum pressure withininternal cavity 112 or forbladder 100. -
Housing 102 may include an elliptical (including circular) shape, a rectangular shape with chamfered corners, or other substantially consistent profile or shape in a given direction.FIGS. 2D-2F illustrate somesuitable housing 102 shapes. For the embodiment ofFIG. 2B ,housing 102 includes a substantially consistent shape in adirection 125 that extends normally away from atube 107 inconnector 104. In one embodiment,housing 102 comprises a transparent section or clear window to allow for visual fuel gauging. - In one embodiment,
housing 102 is integrally formed to prevent disassembly ofhousing 102. In this case,walls 110 may be permanently bonded or extruded from a common material in one piece such that access intohousing 102 is only gained through destruction ofwalls 110 andhousing 102. -
Connector 104 interfaces with a mating connector 140 (seeFIG. 2B ) included in an external device. Together,connector 104 andmating connector 140 permit transfer offuel source 17 betweenbladder 100 and the external device. Whenmating connector 140 is included infuel processor 15 or a device that includesfuel processor 15,connector 104 andmating connector 140 interface to permit transfer offuel source 17 fromstorage device 16 to thefuel processor 15. Alternatively, whenmating connector 140 is included in a hydrogen fuel source refiller,connector 104 andmating connector 140 interface to permit transfer offuel source 17 from the refiner tostorage device 16. Interface betweenconnector 104 andmating connector 140 may comprise any relationship and mating structures that permit fluid communication between the two connectors.Connector 104 and/ormating connector 140 may also include mechanical coupling to secure the interface, such as latching elements that bindconnector 104 andmating connector 140 together until physically released.Connector 104 andmating connector 140 may also each include electrical leads that contact when the connectors are attached to enable electrical and digital communication. -
Connector 104 andmating connector 140 each comprise a geometry that at least partially matches geometry of the other.Exemplary connector 104 andmating connector 140 geometries are described below with respect toFIGS. 2D-2G . - In one embodiment,
connector 104 incorporates a quick disconnect that permitsstorage device 16 to be readily removed by pulling onhousing 102. This separatesconnector 104 andmating connector 140 and detaches any electrical links and plumbing responsible for fluid communication betweenstorage device 16 and the device includingmating connector 140. Asecond storage device 16 with aquick disconnect connector 104 may then be readily inserted back intomating connector 140. The quick disconnect thus allows rapid replacement ofstorage device 16 with anotherstorage device 16 when fuel source volume levels are low. Thequick disconnect connector 104 includes one port or multiple ports according to the plumbing needs of storage device 16 (e.g., fuel provision and a scrubbing bed). Aquick disconnect connector 104 may also include other features to control removal requirements such as two handed operation or a high force actuator. Commercially available quick disconnect connectors are available from a variety of vendors. One suitable quick disconnect connector is model number QDC101 as provided by Beswick of Greenland, N.H. As will be described in further detail below,storage device 16 may also include a hot swappable capability that improves quick disconnect usage forconnector 104 andmating connector 140. -
Connector 104 andmating connector 140 may provide an automatic shutoff capability whendevice 16 is removed fromsystem 202. In this case, each only open when connected to the other and whendevice 16 interfaces withdevice 202. In one embodiment,device 16 comprises a small sponge or swab located on or nearconnector 104 to collect any fuel leakage during device connection or disconnect. - In one embodiment, one of
connector 104 andmating connector 140 includes a ‘male’ designation and configuration while the other includes a ‘female’ designation and configuration. The male configuration includes portions of the connector that protrude, such as one or more pins or electrical leads. The female configuration includes portions of the connector that receive the male portions, such as holes electrically lined to receive the male portion and facilitate electrical communication. As shown inFIG. 2G ,connector 104 onstorage device 16 includes a female configuration that recesses withinhousing 102. Since it is recessed,connector 104 cannot be knocked off during rough handling.Mating connector 140 is configured on a side portion of an OEM device (i.e., a laptop computer). As will be described in further detail below,mating connector 140 is also included in refilling hardware that refillsstorage device 16 withfuel source 17. -
Memory 106 stores information relevant to usage ofstorage device 16.Memory 106 may comprise a mechanical, electrical and/or digital mechanism for information storage. In one embodiment,memory 106 comprises a digital memory source that permits an external controller to read and write from the digital memory. In another embodiment,memory 106 includes a mechanical device. One suitable mechanical device comprises “break-off” pins 158 (seeFIG. 2D ). Other forms ofmechanical memory 106 may comprise discs or rods which are removed or otherwise manipulated every time astorage device 16 is refilled. For the embodiment shown inFIG. 2D ,memory 106 is external tohousing 102 and comprises a visible identification tag that uniquely identifiesstorage device 16. Various types of external identification tags are known in the art and may be used with this invention. Two examples of identification identifier tags include magnetic recording devices and optical bar codes. - In one embodiment,
storage device 16 is considered ‘smart’ sincememory 106 stores information related to the performance, status and abilities ofstorage device 16. A digital memory allows an external controller or logic to read and write information relevant to usage of the storage device tomemory 106. Reading from adigital memory 106 allows reception and assessment of information inmemory 106 to improve usage ofstorage device 16. For example, a computer that receivesstorage device 16 may inform a user that thestorage device 16 is empty or how much fuel is left (or how much time on the system is available based on its power consumption and the amount of fuel remaining). Writing to adigital memory 106 allows information inmemory 106 to be updated according tostorage device 16 usage. Thus, if a user nearly depletesfuel source 17 instorage device 16 while powering a computer, the next user may be informed after the first computer writes an updated amount offuel source 17 remaining instorage device 16 intomemory 106. -
Storage device 16 specifications stored inmemory 106 generally do not change withdevice 16 usage and may comprise a) a fuel type stored in the storage device whendevice 16 is dedicated to service a particularhydrocarbon fuel source 17, b) a model number forstorage device 16, c) an identification signature for the manufacturer ofstorage device 16, d) manufacture date, and e) a volume capacity forbladder 100 orstorage device 16. The model number ofdevice 16 allows it to be distinguished from a number of similar devices. - Transient information stored in
memory 106 that changes according to the status and usage ofstorage device 16 may comprise a) hydrogen fuel mixture information, b) a number of refills provided tostorage device 16 whendevice 16 is configured for re-usable service, c) the last refill date, d) the refilling service provider that refilledstorage device 16 when the device is configured for re-usable service, e) usage history according to a storage device identification, and f) a current volume for the storage device. - Referring now to
FIG. 2B ,storage device 16 comprises abladder 100 with acollapsible bellows configuration 126,housing 102,connector 104,memory 106,air vent 132,filter 134,pressure relief valve 136,fire retardant foam 138,mechanical shield 142, andfuel source filter 144.Connector 104 comprisestube 107 andfemale bay 117.Storage device 16 connects to alaptop computer 202, which includesmating connector 140.Mating connector 140 comprisestube 109,reserve volume 302 andmale housing 113. -
Mating connector 140 interfaces withconnector 104 to permit transfer ofhydrogen fuel source 17 fromstorage device 16 tolaptop computer 202. In one embodiment,storage device 16 resembles a battery-sized cartridge including afemale connector 104 that receives amale mating connector 140.Male housing 113 ofmating connector 140 fits snugly into afemale bay 117 of connector 104 (seeFIG. 2G for side view of a bay 117). The fit provides mechanical support for the interface betweenmating connector 140 andconnector 104. Distal end oftube 107 instorage device 16 and a distal end oftube 109 inmating connector 140 align whenconnector 104 andmating connector 140 join. In a specific embodiment,tube 109 comprises a pointed end that pierces intotube 107 andtube 109 comprises a diameter that snugly fits intotube 107 whenconnector 104 andmating connector 140 are attached. - When
mating connector 140 andconnector 104 are joined as shown, a pump run by afuel cell system 10 withinlaptop computer 202 draws fluid frombladder 100 into thefuel cell system 10. More specifically,fuel source 17 travels frombladder 100, throughtube 107 inconnector 104, into and throughtube 109 inmating connector 140, and throughtube 109 inlaptop computer 202 to afuel processor 15 included therein. -
Connector 104 andmating connector 140 may also include electrical connectivity for digital communication betweenmemory 106 and a processor or controller (seeFIG. 4 ) onlaptop computer 202.FIG. 2F illustrates femaleelectrical slots 155 onconnector 104 b. Amating connector 140 forconnector 104 b then includes male leads (not shown) that fit intoslots 155 for electrical communication betweenlaptop computer 202 andstorage device 16. - For the embodiment of
FIG. 2B ,bladder 100 comprises acollapsible bellows design 126. Oneend 127 a ofbellows 126 attaches and opens totube 107, while theopposite end 127 b is free to move indirection 125. Whenbladder 100 fills withfuel source 17,free end 127 b moves indirection 125 and bellows 126 expands and increases in volume. Whenbladder 100 losesfuel source 17,free end 127 b moves opposite todirection 125 and bellows 126 collapses and decreases in volume.Free end 127 b andbladder 100 thus compresses towards the location wherefuel source 17 is outlet and where negative pressure is created to contract or collapse bellows 126 (tube 107 andconnector 104 in this case).FIG. 2C illustrates abellows configuration 126 at its maximum volume. As shown inFIG. 2B ,bladder 100 is less than half full offuel source 17 and assumes less than half the space ininternal cavity 112.Bellows 126 comprisescollapsible rings 128 that fold asbellows 126 expands (the angle of eachring 128 opens) and asbellows 126 collapse (the angle of eachring 128 closes).Bellows 126 may comprise plastic or Nickel, for example.Bellows 126 may be custom molded or electroformed. Similarly designed bellows are used to protect tubular warp in machine tools, for example. Servometer Corp. of New Jersey provides several suitable commercially available nickel bellows. -
Storage device 16 includes anair vent 132 inhousing 102 that allows air to enter and exit ininternal cavity 112 withinhousing 102 asbladder 100 changes in volume.Air vent 132 comprises one or more holes or apertures in awall 110 ofhousing 102. In operation, asfuel source 17 is consumed and drawn fromstorage device 16,bladder 100 collapses and creates a negative pressure ininternal cavity 112 outside ofbladder 100. Based on this negative pressure caused by a decreasing volume of bladder 100 (or increasing volume ofinternal cavity 112 outside bladder 100), air enters throughair vent 132 intointernal cavity 112 and displaces the decreasing volume ofbladder 100. This prevents the pressure offuel source 17 inbladder 100 from decreasing and affecting the ability ofstorage device 16 to providefuel source 17 at a substantially constant pressure. When fillingstorage device 16, positive pressure caused by an increasing volume offuel source 17 andbladder 100 causes air to exit throughair vent 132. Since walls ofbladder 100separate fuel source 17 withinbladder 100 from air ininternal cavity 112, air incavity 112 does not enterbladder 100 or mix withfuel source 17. - A
filter 134 spans the cross section ofair vent 132 and intercepts air passing throughair vent 132. In one embodiment,filter 134 comprises a hydrophobic and gas permeable filter that prevents foreign materials from enteringstorage device 16. Materials blocked byfilter 134 may include liquids and particles such as undesirable oils and abrasives that may affectstorage device 16 performance. The hydrophobic filter also preventsfuel source 17 from escapinghousing 102 in the event thatbladder 100 develops a leak.Filter 134 may comprise micro porous Teflon or another micro porous material such as Teflon coated paper. A sintered metal filter, for example one with a 3 micron pore size, may also be used. Onesuitable filter 134 includes micro porous “Gore Tex” Teflon as provided by WL Gore Associates of Elkton, Md. -
Mechanical shield 142 spans and coversair vent 132 and prevents foreign bodies from enteringhousing 102 throughair vent 132 anddamaging bladder 100. In one embodiment,air vent 132 is recessed into awall 110 such thatmechanical shield 142 is flush with the outer surface ofhousing 102. As shown,filter 134 is located internal to shield 142 such thatshield 142 mechanically protectsfilter 134. In one embodiment,mechanical shield 142 includes a flame suppressor or a suitable means of flame suppression. Themechanical shield 142 then prevents flame propagation into or out frominterior cavity 112. One suitablemechanical shield 142 includes cut to size 180×180 mesh stainless steel screen as provided by McNichols of Tampa, Fla. -
Pressure relief valve 136 limits pressure instorage device 16. More specifically,pressure relief valve 136releases fuel source 17 frombladder 100 when the pressure withinbladder 100 reaches a threshold pressure. The threshold pressure refers to a pressure forbladder 100 that represents the upper limit of operational pressure forfuel source 17 use instorage device 16. Threshold pressures from about 5 psig to about 25 psig are suitable for somefuel sources 17 andstorage devices 16. A threshold pressure of about 15 psig is suitable in many cases. Other suitable threshold pressures may relate to the boiling point of thefuel source 17, which ranges from about 2 Atm to about 10 Atm. Thus, if temperature forstorage device 16 rises above the boiling point offuel source 17, the threshold pressure is reached andpressure relief valve 136releases fuel source 17 frombladder 100. During normal operation and storage, the partial pressure offuel source 17 inbladder 100 is less than the threshold pressure andpressure relief valve 136 is not used. In the event that pressure offuel source 17 inbladder 100 rises above the threshold pressure,pressure relief valve 136releases fuel source 17 frombladder 100, thereby limiting the pressure withinbladder 100. - In a specific embodiment,
pressure relief valve 136 comprises a sprung diaphragm mechanism. The sprung diaphragm includes a diaphragm and a spring that attaches to the diaphragm. Pressure inbladder 100 pushes the diaphragm outward against the spring force. At the threshold pressure, the diaphragm opens a port—a small hole that opens outside ofhousing 102—to permit the release offuel source 17 frombladder 100. Spring selection permits a designer to control the threshold pressure at which the port opens andfuel source 17 escapes. In another specific embodiment,pressure relief valve 136 comprises a burst disk mechanism that includes a thin diaphragm. The diaphragm breaks outward when pressure inbladder 100 rises above the threshold pressure. The diaphragm break and the resultant opening releasesfuel source 17 frombladder 100. For either design, the port or opening may be configured to direct venting fuel vapors away fromstorage device 16 and into a ventilated area when installed in an electronics or OEM device. - A
fuel source filter 144intercepts fuel source 17 as it leavesbladder 100 and before it leavesconnector 104. As shown,filter 144 spans an entrance totube 107 frombladder 100.Fuel source filter 144 removes any contaminants or chemicals added to fuelsource 17 for storage inbladder 100 anddevice 16. In one embodiment,fuel source 17 comprises anodorant 150, abitterant 152 and/or acolorant 154 mixed therein. Iffuel source 17 comprises an odorless liquid,odorant 150 provides olfactory stimulus to inform a person that fuelsource 17 has escapedbladder 100 andstorage device 16 via a path other than throughtube 107 andfilter 144. Twosuitable odorants 150 includes trimethyl amine at 1-10 ppm in methanol and ethyl mercaptan at 1-7 ppm weight in methanol.Fuel source filter 144 removesodorant 150 fromfuel source 17 when the fuel source leavesbladder 100 throughtube 107. - If
fuel source 17 comprises a colorless liquid,colorant 154 provides visual stimulus to inform a person that fuelsource 17 has leaked or escaped frombladder 100 via a path other than throughtube 107 andfilter 144.Suitable colorants 154 include acid blue 9 at 1 ppm, table 5-4 food dye, and bright green/blue erioglaicine disodium salt as provided by Dudley Chemical Corp of Lakewood, N.J.Fuel source filter 144 removescolorant 154 fromhydrogen fuel source 17 when the fuel source leavesbladder 100 throughtube 107. - If
fuel source 17 comprises liquid with no taste, abitterant 152 may be added to provide taste stimulus that informs a person that fuelsource 17 has escapedbladder 100 via a path other than throughtube 107 andfilter 144. Onesuitable bitterant 152 includes Denatonium Benzoate at 1-50 ppm (20-50 ppm is adversely bitter) as provided by Bitrex of Edinburgh, UK.Fuel source filter 144 removes bitterant 152 fromhydrogen fuel source 17 whenfuel source 17 leavesbladder 100 throughtube 107. Onesuitable filter 144 for removingodorant 150,bitterant 152 and/orcolorant 154 includes an ultra-pure polyethersulfone membrane. Anothersuitable filter 144 for removingodorant 150,bitterant 152 and/orcolorant 154 fromfuel source 17 includes 0.1 Advantage PS C-7012 filter as provided by Parker Hanafin Corp. - A
fire retardant foam 138 is disposed inbladder 100.Foam 138 is compliant and conforms in size to the size ofbladder 100. Thus, asbladder 100 collapses,foam 138 compresses. In one embodiment,foam 138 acts as a wicking foam that directs some flame behavior instorage device 16. Onesuitable foam 138 is polyurethane mil Spec Mil-B-83054 as provided by Foamex of Lindwood, Pa. - In one embodiment,
memory 106 comprises a wireless identification (ID) tag. This allowsmemory 106 to communicate with an external device, such as hydrogenfuel source refiner 162 described inFIG. 3 . In this case, the external device includes an interrogator that probesmemory 106 via wireless communication whenstorage device 16 is in range of the interrogator. The interrogator may include any hardware for performing this function such as a computer, transceiver and interrogator antenna. Coupling between the interrogator andstorage device 16 may occur via radio frequency (RF) or microwave frequency radiation. When probed by the interrogator,storage device 16 replies with its identification (as stored in a digital or electrical memory 106) and any other information stored inmemory 106, such as the status of any sensors used instorage device 16 to monitor health of the device and sensors that detect the volume of fuel source inbladder 100. Thestorage device 16 identification provides a means for automated logging of data corresponding to the status ofstorage device 16. The identification also facilitates inventory logging of information fornumerous storage devices 16. - In one embodiment, the interrogator provides power to
storage device 16. The power is transmitted by RF waves, for example, and received by a rectifier instorage device 16 that rectifies the signal, thereby providing sufficient DC power to operate any circuitry ofstorage device 16. A transponder included instorage device 16 responds to a wireless stimulus. The transponder transmits signals when actuated by a signal from an external interrogator. In some cases, the transponder includes an amplifier for increasing the strength of a received incident signal, a modulator for modifying the signal with information stored bymemory 106, and an antenna or antennas for receiving and transmitting signals. - Wireless ID tags are commercially well known and there exists numerous manufacturers that currently offer a wide selection of RFID tags. These tags are either passive (typically operating near 125 kHz) or active (often operating near 2.45 GHz). Major manufacturers include Texas Instruments of Dallas, Tex. and Motorola of San Jose, Calif. or Alien Technologies of San Jose, Calif. Products are available for inventory control, product labeling, etc. For example,
storage device 16 may use a commercial RFID tag, such as a 125-kHz tag supplied by Texas Instruments of Dallas, Tex., which includes a microchip formemory 106 and inductor for wireless communication. -
Storage device 16 may also comprise a sensor that monitors a condition related to the health or functioning ofstorage device 16. In one embodiment, the sensor comprises awire 156 that runs about an inside surface ofhousing 102 or is formed within awall 110 housing 102 (seeFIG. 2C ). An electrical state or performance ofwire 156 provides an indication of the health ofhousing 102. Mechanical damage, cracking or structural compromise ofhousing 102 affectswire 156—mechanically and electrically. More specifically, whenwire 156 breaks, stretches or loses contact due to mechanical changes housing 102, an electrical signal sent throughwire 156 changes. The according change may be read and assessed. Thus, a break inwire 156 may be read by non-transmittance of a signal. Changes in electrical resistance ofwire 156 may also provide an indication of health. In one embodiment, the sensor relies on external (e.g., RFID) probing to assess the state ofwire 156 and health ofhousing 102. In this case, the interrogator powersmemory 106 to test the resistance ofwire 156. TheRFID memory 106 then responds with a signal indicative of the status ofwire 156. Although the sensor is shown as asingle wire 156, it is understood that more complex designs may comprise filament networks that extend two dimensionally throughouthousing 102. Each filament may then be probed for its electrical status, e.g., resistance to provide a meshed status check of integrity and health ofhousing 102 andstorage device 16. -
FIG. 2D illustrates a front view of fuelsource storage device 16 a in accordance with one embodiment of the present invention.FIG. 2E illustrates a front view of astorage device 16 b that is partially compatible withstorage device 16 a.FIG. 2F illustrates a front view of astorage device 16 c that is not compatible withstorage device 16 a.FIG. 2G illustrates a side view of astorage device 16 c. -
Connector 104 and/ormating connector 140 may include a ‘keyed’ configuration that provides interface selectivity. For example,connector 104 may comprise a configuration unique to a particular hydrogen fuel source (e.g., methanol). In this case,mating connector 140 offers an exclusive interface that only receives aconnector 104 for a methanol basedstorage device 16. This keying system prevents the wrong fuel type from being installed in a device that cannot accept that fuel, e.g., gasoline burns at a higher temperature and may not be suitable for use in all methanol fuel processors. This keying system also preventsstorage device 16 from being refilled with the wronghydrogen fuel source 17. - For example,
storage device 16 a ofFIG. 2D includes acircular connector 104 a that interfaces with a circular mating connector (not shown). Similarly,storage device 16 b ofFIG. 2E includes acircular connector 104 a of the same dimensions that interfaces with the same circular mating connector as that employed forconnector 104 a. Thestorage device 16 c ofFIG. 2F includes arectangular connector 104 b that would not interface with the same circular mating connector.Circular connectors 104 a may be used for methanol fuel mixtures of different blends for example, whilerectangular connector 104 b is used for ethanol. - The keyed configuration of connector also allows for variation of one of
connector 104 ormating connector 140, while the other remains constant. This controlled variability has numerous commercial applications. In one commercial system,connector 104 may change slightly whilemating connector 140 remains constant. Acommon mating connector 140 may receivedifferent storage devices 16 that share aconnector 104 a configuration. Thedifferent storage devices 16 may be produced by different manufacturers and may include varying volumes orother storage device 16 features. This permits competition for the provision ofstorage devices 16 but standardization of their interface. In another commercial application, an electronics device manufacturer such as Dell specifies acustom mating connector 140 configuration (e.g., a circular configuration used in their laptop computers and other electronics devices). Allstorage devices 16 that service these electronics devices must then include aconnector 104 that matches Dell'scustom mating connector 140 configuration. The electronics device manufacturer may then control who manufacturersstorage devices 16 andconnectors 104 for use with their electronics devices.Keyed connectors 104 a for one electronics device manufacturer may also be designed to not fit amating connector 140 for another computer manufacturer, e.g., Apple employs arectangular configuration 104 b. -
Custom connector 104 andmating connector 140 configurations may vary based on geometry, dimensions, depth and size for example. Aconnector 104 ormating connector 140 may also include one ormore features 149 that distinguish a custom connector or mating connector. As shown inFIG. 2E , feature 149 is a tab that extends into thefemale bay 117 of connector and mechanically distinguishesstorage device 16 b fromstorage device 16 a. -
Connector 104/mating connector 140 configuration selectivity may also be implemented to distinguish developing technology infuel cell system 10 orstorage device 16. By changingmating connector 140 to receive onlycertain connectors 104, the present invention permits continuing development offuel cell system 10 orstorage device 16 and ensures rejection ofprevious storage device 16 models that are no longer suitable. For example,storage device 16 b may represent a newer version ofstorage device 16 a that is mechanically distinguished byfeature 149. An electronics device that receivesstorage devices 16 may include amating connector 140 that mechanically rejectsstorage device 16 a based omission offeature 149.Memory 106 may also be digitally read to indicate incompatibility. - The keyed configurations shown in
FIGS. 2D-2F may also be implemented forparticular fuel source 17 types. For example,storage device 16 a andconnector 104 a may designate a methanol fuel mixture ‘A %’, whilestorage device 16 b and feature 149 designate a methanol fuel mixture ‘B %’ andstorage device 16 c andconnector 104 b designates an ethanol fuel mixture. -
Storage devices 16 a also comprise “break-off” pins 158 that form amechanical memory 106.Pins 158 indicate the number of refills for eachstorage device 16. Eachtime storage device 16 is refilled, the refiner breaks apin 158. When all the pins have been removed, a mating connector toconnector 104 will not acceptstorage device 16.Pins 158 may comprise plastic and be molded into thecartridge housing 102 or toconnector 104. - In one embodiment,
storage device 16 is intended for disposable use. In this case, a user purchases astorage device 16 with a full complement of methanol and disposes ofstorage device 16 after it is emptied.

FIG. 3 Illustrates asystem 160 for providing a refillable hydrogen fuelsource storage device 16 in accordance with one embodiment of the present invention.System 160 comprisesstorage device 16 and a hydrogenfuel source refiner 162. - Hydrogen
fuel source refiner 160 includesmating connector 140 and is configured to providehydrogen fuel source 17 tostorage device 16 when theconnector 104 is coupled tomating connector 140.Connector 104 andmating connector 140 interface to permit transfer offuel source 17 fromrefiner 160 tostorage device 16.Refiller 160 comprises afuel reserve tank 164 that storeshydrogen fuel source 17. Tank is suitably size to refuelnumerous storage devices 16. Apump 166 receives control signals from arefiller controller 168 that controls functioning ofrefiner 160 based on stored commands inrefiner memory 170.Refiller memory 170 may also include a database that stores information for eachstorage device 16 serviced byrefiner 160. - A
line 172 transportsfuel source 17 fromtank 164 tostorage device 16. More specifically, pump 166 movesfluid fuel source 17 fromtank 164 throughtube 109 inmating connector 140, into and throughtube 107 inconnector 104, and intobladder 100 for storage therein. Althoughrefiner 160 is shown refilling asingle storage device 16, it is understood thatrefiner 160 may comprise multiple ‘bays’ that each include amating connector 140 and plumbing to refill asingle storage device 16.Refiller 160 may also includemultiple tanks 164 that provideddifferent fuel sources 17, such as different fuel sources (e.g., methanol or ethanol) or different fuel mixtures. -
Controller 168 also communicates withmemory 106 vialine 174, which travels fromcontroller 168, through electrical connectivity provided byconnector 104 andmating connector 140 and tomemory 106.Controller 168 may also communicate withmemory 106 via wireless means as described above ifcontroller 168 andmemory 106 both include such capability.Refiller 160 includes aninterrogator 176 to communicate wirelessly with astorage device 16.Interrogator 176 comprises a transceiver and antenna based on the communication frequency employed. -
Controller 168 reads from and writes tomemory 106.Controller 168 may read and store the usage history of adigital memory 106. Whenstorage device 16 includes a mechanical memory such as the break-offpins 158 described above,refiller 162 checks if there are anypins 158 remaining (either mechanically or electronically). If all the pins have been removed,refiner 162 does not acceptstorage device 16.Controller 168 may also check the status of any sensors onstorage device 16 used to monitor health of thedevice 16, such as an RDIF sensor that detects housing integrity. This helps a re-filling services provider determine ifstorage device 16 can be simply be refilled, or if it needs to refurbished as well. Viacontroller 168 and stored logic that dictates responses to information read frommemory 106,refiller 162 is thus configured to detect a defect instorage device 16 and not transferhydrogen fuel source 17 tostorage device 16 when a predetermined memory element is present. Memory elements may include use of a pressure relief valve or information related to the status of any sensors onstorage device 16. -
Controller 168 may also write intomemory 106 information such as: the hydrogen fuel mixture information stored therein, an updated number of refills provided tostorage device 16, the refill date, the refilling service provider, and a volume for the storage device. Whenstorage device 16 includes a mechanical memory such as the break-offpins 158 described above,refiller 162 breaks apin 158 upon refill completion. -
Refillable system 160 allows distribution of thehydrogen fuel source 17 to be handled flexibly. One approach is to distributerefillable storage devices 16 similar to the distribution of batteries. A consumer purchases a desiredstorage device 16 at a retail outlet, such as a department store, super market, airport kiosk or drug store etc.Storage device 16 selection may vary based onfuel source 17 capacity,fuel source 17 type or other features such as connectivity and smart features.Spent storage devices 16 may be dropped off at the any of the above locations for reuse, and shipped to a refilling services provider for refurbishment and refill. - When
storage device 16 comprises a hydrogen fuel cleaning system,refiller 162 may also rejuvenate or check for replacement of the cleaning system. For the scrubbing bed as described below with respect to filter 220,refiller 162 rejuvenates the cleaning system by forcing hydrogen through the bed (e.g., using hydrogen in tank 164). The scrubbingbed filter 220 may also be replaced with a new bed when thestorage device 16 is refilled. - Refilling
system 160 allows ahydrogen fuel source 17 refilling provider to control refilling ofstorage devices 16.Connectors 104 that require specific parts onmating connector 140 to complete interface and permit fluid transfer intostorage device 16 also prevent free tampering and addition of fluids tostorage device 16. Refillingsystem 160 also provides a business model for distribution ofstorage devices 16. Refillingsystem 160 also permits thehydrogen fuel source 17 refilling provider to certify fuel blends, monitor the number of refills for aparticular storage device 16, and validatestorage device 16 for consumer or manufacturer confidence. -
FIG. 4 shows a schematic illustration of asystem 200 for producing electrical energy for a portable electronics device in accordance with one embodiment of the present invention.System 200 comprisesfuel processor 15 andfuel cell 20 included within anelectronics device 202 and a hydrogen fuelsource storage device 16 coupled toelectronics device 202 viaconnector 104 andmating connector 140.Electronics device 202 may comprise any portable or stationary electronics device or power application that relies on a fuel cell to generate electrical energy. - In one embodiment,
fuel processor 15 andfuel cell 20 are incorporated into electronics device 202 (within its volume and outer housing) as an integral module, andstorage device 16 is removable allowing for instant recharging. Fuel cell poweredlaptop computers 202 may comprise slightly modified existing products, withfuel processor 15 andfuel cell 20 and related system components fitted generally into the space provided for a battery pack.Mating connector 140 is included in this allocated space for connection tostorage device 16.Storage device 16 mechanically interfaces withelectronics device 202. In one embodiment,connectors storage device 16 andelectronics device 202. In another embodiment,electronics device 202 includes a mechanical slot thatstorage device 16 fits and slides into. In one embodiment, an external cartridge-mounting bracket is provided to allow forlarger storage devices 16 to be used. - When
connector 104 andmating connector 140 interface, fuelcell system controller 214 digitally communicates withmemory 106 usinglink 217 for bi-directional communication therebetween. In another embodiment,controller 214 uses a wireless interrogator to communicate with an RFID antennae andmemory 106 included instorage device 16.Controller 214 may read any information stored inmemory 106 such as a fuel type stored in thestorage device 16, a model number forstorage device 16, a volume capacity forbladder 100 orstorage device 16, a number of refills provided tostorage device 16, the last refill date, the refilling service provider, and a current volume for the storage device. In one commercial application,different bladder 100 volumes andstorage device 16 configurations are offered based on different laptop computer manufacturers and models for a particular manufacturer. The volume may be configured to meet a specific run time requirement for a particular laptop model, for example. In this case,controller 214 estimates the remaining power instorage device 16 by comparing thefuel source 17 level since last use or refill against a consumption rate for a particular laptop computer. -
Controller 214 may also write transient information tomemory 106, such as an updated volume for the storage device. Thecontroller 214 communicates with amain controller 210 forcomputer 202 andcomputer memory 218 viacommunications bus 212.Computer memory 218 may store instructions for the control offuel system 10 such as read and write protocol and instructions for communication with adigital memory 106. -
System 200 also comprises a hydrogen fuel cleaning system. As shown,storage device 16 comprises afilter 220 in fluidic communication withhydrogen 224 output byfuel processor 15.Filter 220 removes contaminants from thehydrogen 224 stream (or reformate) before receipt byfuel cell 20. The reformate often includes hydrogen, carbon dioxide, carbon monoxide and other small particulates.Filter 220 may remove carbon monoxide, un-converted methanol vapor and/or hydrogen sulfide (among others). As shown, line 226 routes reformate 224 output by a hydrogen outlet offuel processor 15, back throughmating connector 140 andconnector 104, intostorage device 16 and throughfilter 220, back out of instorage device 16 and to an anode inlet offuel cell 20. In a specific embodiment,filter 220 comprises a carbon monoxide scrubbing catalyst or absorbent arranged in a bed thathydrogen 224 stream passes through. The bed is filled with a material, such as activated carbon, potassium permanganate or cupric chloride (CuCl2). The catalyst or absorbent absorbs CO, methanol vapor or H2S. As described above, the scrubbing bed may be rejuvenated by passing hydrogen through the bed when thestorage device 16 is refilled. Or the scrubbing bed may be replaced with a new bed when thestorage device 16 is refilled.Filter 220 simplifies chemical management forfuel processor 15 and increases the performance offuel cell 20.Filter 220 also reduces poisoning of thefuel cell 20 catalysts with un-converted methanol vapors, by trapping the vapors prior to thehydrogen 224 stream enteringfuel cell 20. In another embodiment, a line routes unused hydrogen fromfuel cell 20 in the anode exhaust tofuel processor 15 to further increase efficiency of the fuel cell system indevice 202. Further discussion of fuel cell systems suitable for use with the present invention are described in commonly owned co-pending patent application entitled “Micro Fuel Cell Architecture” naming Ian Kaye as inventor and filed on Jun. 25, 2004, which is incorporated by reference for all purposes. -
Power management 216 controls power provision byfuel cell system 10 andelectrochemical battery 222. Thus,power management 216 may informcontroller 214 how much power is needed forlaptop computer 202 operation andcontroller 214 responds by sending signals tofuel cell 20,fuel processor 15 and a pump that draws fuel fromstorage device 16 to alter fuel cell power production accordingly. Iffuel cell system 10 runs out offuel source 17, thenpower management 216 switches to electrical power provision frombattery 222. - A
spare storage device 16 d is included insystem 200.Storage device 16 d shares aconnector 104 withstorage device 16 a (currently plugged in).Storage device 16 d comprises a dualinternal compartment internal wall 110 d.Internal compartment 112 a includes afirst bladder 100 b whileinternal compartment 112 b includes asecond bladder 100 b. The dual bladder design ofstorage device 16 d provides extended power back up forsystem 200. -
System 200 may also be configured for ‘hot swappable’ capability. As the term is used herein, hot swapping ofstorage device 16 refers to removingstorage device 16 from a fuel processor or electronics device it provideshydrogen fuel source 17 to, without shutting down the receiving device or without compromising hydrogen fuel source provision to the receiving device for a limited time. A hot swappable system implies fuel source provision whenconnector 104 andmating connector 140 are separated. Referring back toFIG. 2A ,electronics device 202 comprises areserve volume 302 that is configured to store thehydrogen fuel source 17 whenconnector 104 andmating connector 140 are separated. - The time that a receiving fuel processor or electronics device may be operated for while
connector 104 andmating connector 140 are separated relates to the amount of fuel inreserve volume 302 and the rate at which the fuel processor or electronics device usesfuel source 17. A maximum volume forreserve volume 302 characterizes the capacity offuel source 17 thatreserve volume 302 can store. In one embodiment,reserve volume 302 includes a maximum volume between about 1 milliliter and about 50 milliliters. A maximum volume between about 1 milliliter and about 4 milliliters may be suitable for some portable electronics applications. - For the
storage device 16 shown inFIG. 2C ,reserve volume 302 comprises the volume oftube 109 between its upstream end where it interfaces withconnector 104 and its downstream end where it opens to thefuel processor 15. The inner diameter oftube 109 may be configured to provide a particular volume maximum forreserve volume 302. In one embodiment,tube 109 comprises plastic tubing with an outer diameter less than ¼ of an inch and a tube wall thickness between about 10 and about 50 mils. - For the
storage device 16 shown inFIG. 2B ,reserve volume 302 comprises a cavity withinconnector 140 that acts as a small reservoir forfuel source 17 entering theelectronics device 202. The cavity permits larger maximum volumes forreserve volume 302. The cavity may alternatively be configured downstream ofconnector 140 within thedevice 202 to receivefuel source 17 fromline 109 after it passes throughconnector 140, e.g., closer to fuelprocessor 15. In this case, the maximum volume forreserve volume 302 includes contributions from both the cavity andtubing 109 traveling from the cavity to the fuel processor. -
Reserve volume 302 may also comprise a bladder that conforms in size and shape to the volume offuel source 17 contained therein. A rubber sac or foldable bellows similar to those described above may be suitable. In one embodiment,tube 109 collapses on itself whenmating connector 140 andconnector 140 are separated. This sealstube 109 and prevent escape of anyfuel source 17 contained therein. - While this invention has been described in terms of several preferred embodiments, there are alterations, permutations, and equivalents that fall within the scope of this invention which have been omitted for brevity's sake. For example, although the present invention has been described with respect to separate
main controller 210 and fuelcell system controller 214, it is understood that these two functional elements may be combined into a common controller. In addition, while the present invention has been described with respect to reformed methanol fuel cell systems that include a fuel processor to convert the fuel source to hydrogen before receipt by the fuel cell, storage devices described herein are also useful for direct fuel source systems such as direct methanol fuel cell systems. In a direct fuel source system, the storage device provides the fuel source directly to the fuel cell without conversion to hydrogen by a separate fuel processor. While not described in detail, such digital control of a mechanical system is well known to one of skill in the art. It is therefore intended that the scope of the invention should be determined with reference to the appended claims.
