Description
Technical field
The present invention relates to fuel cell, relate in particular to the fuel cell that has air temperature modification and humidity stabilization device.
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 car, ship, can be used as movable type, fixed Blast Furnace Top Gas Recovery Turbine Unit (TRT) again.
When used in proton exchange membrane fuel cell is done car, ship power system or movable type and stationary power generation station, must comprise battery pile, fuel hydrogen supply system, air supply subsystem, cooling heat dissipation subsystem, control and electric energy output various piece automatically.
Fig. 1 is at present typical fuel cell generation, and 1 is fuel cell pack in Fig. 1, and 2 are storage hydrogen bottle or other hydrogen-storing devices, 3 is pressure-reducing valve, and 4 are air filtration worry device, and 5 is the air compression feeding mechanism, 6 is the hydrogen Water-vapor seperator, 6 ' is the air Water-vapor seperator, and 7 is water tank, and 8 is cooling water circulating pump, 9 is cooling water radiator, 10 is the hydrogen circulating pump, and 11 is the hydrogen humidifying device, and 12 is the air humidification device.
According to the at present typical integrated and operation logic of fuel cell generation, must be to hydrogen and air that fuel cell pack is carried through voltage stabilizing and through humidifying device (11,12) after, become humid air, the hydrogen that reaches certain relative humidity and temperature and then enter electrochemical reaction takes place in the fuel cell pack.Otherwise the dry or inadequate air of humidification, when hydrogen is carried to fuel cell pack, excessive air, hydrogen can cause the proton exchange membrane dehydration in core component-membrane electrode in the fuel cell pack, the proton exchange membrane dehydration will cause internal resistance of fuel cell sharply to increase, and runnability sharply descends.
Being applied to the air temperature modification of Proton Exchange Membrane Fuel Cells and the method for moisture stable at present mainly is according to variations such as ambient temperature, fuel cell output current, control temperature, the humidity that enters fuel battery air by the switching time of regulating the humidification turning barrel, the method for humidification motor speed, use the aqueous water in the moisture separator separation of air.
But present technical scheme has following technological deficiency to the air that fuel cell pack is carried through directly entering fuel cell pack generation electrochemical reaction after becoming the humid air that reaches certain relative humidity and temperature behind the humidification:
Owing to be subjected to the influence of external environment, when ambient temperature changes and outside air relative humidity variations greatly the time, under same operating mode varying environment, air themperature of sending from the humidification turning barrel and the humidity controlling value that will depart from objectives, can not guarantee to enter the constant of fuel battery air temperature, humidity, cause the fuel cell operation unstable properties.Therefore the have to variation that allows fuel cell conform by the Control Parameter of revising humidification turning barrel and humidification motor has caused the inconvenience in the control.
