Description
Technical field
The present invention relates to fuel cell, relate in particular to a kind of fuel battery humidification device efficiently.
Background technology
Electrochemical fuel cell is a kind of device that hydrogen and oxidant can be changed into electric energy and product.The internal core parts of this device are membrane electrode (Membrane Electrode Assembly are called for short MEA), and membrane electrode (MEA) is made up of as carbon paper a proton exchange membrane, two porous conductive materials of film two sides folder.The catalyst that contains the initiation electrochemical reaction of even tiny dispersion on two boundary faces of film and carbon paper is as the metal platinum catalyst.The membrane electrode both sides can electrochemistry will take place with conductive body to be sent out and answers the electronics that generates in the process, draws by external circuit, constitutes current circuit.
At the anode tap of membrane electrode, fuel can pass porousness diffusion material (carbon paper) by infiltration, and electrochemical reaction takes place on catalyst surface, lose electronics, form cation, cation can pass proton exchange membrane by migration, arrives the other end cathode terminal of membrane electrode.At the cathode terminal of membrane electrode, contain the gas of oxidant (as oxygen), as air, pass porousness diffusion material (carbon paper), and the generation electrochemical reaction obtains electronics on catalyst surface, forms anion by infiltration.The cation of coming in the anion and the anode tap migration of cathode terminal formation reacts, and forms product.
Adopting hydrogen is fuel, and the air that contains oxygen is in the Proton Exchange Membrane Fuel Cells of oxidant (or pure oxygen is an oxidant), and fuel hydrogen has just produced hydrogen cation (or being proton) in the catalytic electrochemical reaction of anode region.Proton exchange membrane helps the hydrogen cation to move to the cathodic region from the anode region.In addition, proton exchange membrane is separated the air-flow and the oxygen containing air-flow of hydrogen fuel, they can not mixed mutually and produces explosion type reaction.
In the cathodic region, oxygen obtains electronics on catalyst surface, forms anion, and moves the hydrogen cation reaction of coming, reaction of formation product water with the anode region.In the Proton Exchange Membrane Fuel Cells that adopts hydrogen, air (oxygen), anode reaction and cathode reaction can be expressed in order to following equation:
Anode reaction: H
2→ 2H
++ 2e
Cathode reaction: 1/2O
2+ 2H
++ 2e → H
2O
In typical Proton Exchange Membrane Fuel Cells, membrane electrode (MEA) generally all is placed in the middle of the pole plate of two conductions, and quarter is milled by die casting, punching press or machinery in the surface that every guide plate contacts with membrane electrode, and formation is the guiding gutter of one or more at least.These guide plates can above metal material pole plate, also can be the pole plate of graphite material.Fluid duct on these guide plates and guiding gutter import fuel and oxidant the anode region and the cathodic region on membrane electrode both sides respectively.In the structure of a Proton Exchange Membrane Fuel Cells monocell, only there is a membrane electrode, the membrane electrode both sides are respectively the baffler of anode fuel and the baffler of cathode oxidant.These bafflers are both as current collector plate, and also as the mechanical support on membrane electrode both sides, the guiding gutter on the baffler acts as a fuel again and enters the passage of anode, cathode surface with oxidant, and as the passage of taking away the water that generates in the fuel cell operation process.
In order to increase the gross power of whole Proton Exchange Membrane Fuel Cells, two or more monocells can be connected into battery pack or be unified into battery pack by the mode that tiles usually by straight folded mode.In straight folded, in-line battery pack, can there be guiding gutter on the two sides of a pole plate, and wherein one side can be used as the anode guide face of a membrane electrode, and another side can be used as the cathode diversion face of another adjacent membranes electrode, and this pole plate is called bipolar plates.A series of monocell connects together by certain way and forms a battery pack.Battery pack tightens together by front end-plate, end plate and pull bar usually and becomes one.
A typical battery stack generally includes: the water conservancy diversion import and the flow-guiding channel of (1) fuel and oxidant gas are distributed to fuel (hydrogen-rich gas that obtains as hydrogen, methyl alcohol or methyl alcohol, natural gas, gasoline) and oxidant (mainly being oxygen or air) in the guiding gutter of each anode, cathode plane equably after reforming; (2) import and export and the flow-guiding channel of cooling fluid (as water) are evenly distributed to cooling fluid in each battery pack inner cooling channel, and the heat absorption that hydrogen in the fuel cell, the exothermic reaction of oxygen electrochemistry are generated is also taken battery pack out of and dispelled the heat; (3) outlet of fuel and oxidant gas and corresponding flow-guiding channel, fuel gas and oxidant gas are when discharging, and portability goes out the liquid that generates in the fuel cell, the water of steam state.Usually, the import and export of all fuel, oxidant, cooling fluid are all opened on the end plate of fuel battery or on two end plates.
Proton Exchange Membrane Fuel Cells can be used as the dynamical system of delivery vehicles such as all cars, ship, can be used as portable, portable, fixed Blast Furnace Top Gas Recovery Turbine Unit (TRT) again.Proton Exchange Membrane Fuel Cells is generally with hydrogen or contain portly hydrogen or alcohols is made fuel.As car, ship power system or movable type, stationary power generation station the time, generally use air oxidant.When used in proton exchange membrane fuel cell is made car, ship power system or movable type, fixed Blast Furnace Top Gas Recovery Turbine Unit (TRT), must comprise battery pile, fuel hydrogen supply system, air supply subsystem, cooling heat dissipation subsystem, control and electric energy output various piece automatically.Wherein the air supply subsystem is absolutely necessary.
Electrochemical reaction is accelerated along with the raising of the fuel in the electrode, oxidant concentration in the Proton Exchange Membrane Fuel Cells.So when using air oxidant, increase in order to make electrode cathode side oxygen concentration, must carry out two aspects, be to increase pressure from air to fuel cell that carry on the one hand, oxygen partial pressure is increased; Be that the water that the electrode cathode adnation becomes is in time run with excessive conveying air band on the other hand, help oxygen like this to the diffusion of electrode reaction zone.So in general improve and supply when excessive when the pressure of air supply, the fuel cell output performance can improve.But must consider to fuel cell and carry the air pressure raising and supply excessive air, can directly cause increasing greatly to the power that fuel cell carries the device (for example air compressor, air pump, air blast) of air to consume.From whole fuel cell power system or electricity generation system, carry the device of air also will consume very big part energy to fuel cell in the system, account for 5～20% of the total output of whole fuel cell system greatly, in order to improve the integral energy efficient of whole fuel cell generation, the energy consumption that reduces air transport device is vital.On the other hand, used proton exchange membrane in the proton exchange membrane fuel cell electrode needs hydrone to preserve moisture in the battery operation process at present.Because have only the proton of abundant aquation just to be free to pass proton exchange membrane, arrive the cathode terminal participation electrochemical reaction of electrode from the anode tap of electrode.Otherwise, when a large amount of excessive dry airs when fuel cell is supplied, easily the moisture subband in the proton exchange membrane is run can't pass freely through proton exchange membrane because the proton aquation is insufficient, cause the electrode internal resistance sharply to increase, electrode performance sharply descends.So, in general need through humidification to the fuel cell air supplied, airborne moisture relative humidity is improved, in order to avoid make the proton exchange membrane dehydration.
The device that can be used for the conveying of Proton Exchange Membrane Fuel Cells electricity generation system air at present mainly contains following two classes:
(1) realizes the compressor of air compression by means of the variation of volume, for example scroll air compressor, screw air compressor etc.;
(2) realize the air pump or the blower fan of air compression by means of the air of rapid movement, for example high pressure, low pressure blower, slide sheet type air pump etc.
This two classes air compression plant is as following common drawback is all arranged when fuel cell is carried the device of air:
(1) when air is compressed, air themperature can sharply raise.Be compressed to 2 atmospheric pressure of absolute pressure from atmospheric air, compressed air themperature can be elevated to more than 100 degree centigrade.When compressed air temperature raise, the efficient of any air compression plant all reduced, or energy consumption increases.
(2) when compressed air reached certain high temperature and spends, when for example being higher than 80 ℃, this compressed air can't directly enter fuel cell operation, because the working temperature of fuel cell generally is no more than 80 ℃.The high hot-air that surpasses temperature of fuel cell, it is very fast with the race of the moisture subband on the proton exchange membrane in the fuel cell to enter fuel cell, and electrode performance is sharply descended.
At present solution to the problems described above be be compressed, the air of elevated temperature is earlier through the outer humidification heat-exchange device of holding concurrently, this device both can be with the air cooling of compressed, elevated temperature below temperature of fuel cell, can relative water humidity be increased near 100% to replenish air hydrone compressed, elevated temperature again.Like this, enter fuel cell operation after, the hydrone on the proton exchange membrane in the fuel cell just can not run by band.But present this method has following shortcoming:
1) system is a many outer humidification holds concurrently heat exchange membranes device has increased the complexity of whole fuel cell as volume, weight and the system of power or electricity generation system.
2) when being compressed, when the air of elevated temperature is held concurrently heat-exchange device by humidification, because air flow resistance increases, causing loss of air pressur, the energy consumption of whole system is increased, energy efficiency descends.In addition, the humidification heat-exchange device of holding concurrently often needs the energy of additive decrementation system, and the energy consumption of whole system is increased, and energy efficiency descends.
The patent (China Patent No. is 02266352.5) of Shanghai supernatural power scientific ﹠ technical corporation application provides a kind of technical scheme, promptly in the air compression plant of fuel cell conveying air, spray into a certain amount of deionized water, the amount that sprays into deionized water should carry air capacity to become certain proportionate relationship to fuel cell with this device, this proportionate relationship mainly makes the compression of this class air compression plant carry air in certain amount to reach both to be cooled to be lower than temperature of fuel cell, reach the purpose of complete humidification again to the relative humidity that meets fuel cell operation, and this deionized water is to utilize the water generation reaction of fuel cell pack itself to obtain through deionized water, therefore, it has saved the outer humidification of the prior art heat-exchange device of holding concurrently, make system configuration simpler, and recycling because of water generation reaction, the operating cost and the energy consumption of fuel cell are further reduced, simultaneously, air compressor machine and high pressure positive blower adopt the humidifying operation of water spray back, battery performance is obviously improved, all very stable when high-power or small-power output.

But this patented technology also has following technological deficiency:
1. carry the compression set of air to spray into aqueous water to fuel cell, the air that air compression plant is carried to fuel cell often can't be with all aqueous water vaporizations.This situation can make aqueous water directly bring fuel cell pack into air, thereby causes some air conducting groove water blockoff in the fuel cell pack.Air conducting groove water blockoff can cause that this fuel-cell single-cell is in the air hunger state, and the electrode when serious in this monocell can be in the antipole state and burn.
2. carry the compression set of air to spray into aqueous water to fuel cell, after compressed and the humidifying, the air that air themperature promptly enters the fuel cell pack reaction advances temperature often can't accurately be controlled, and this can influence the stability of the operation of fuel cell pack.
