Technical field
The present invention relates to fuel cell, relate in particular to and to make the hydrogen that enters reaction or the fuel cell of air themperature and moisture stable.
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.

1. before dry air, fuel hydrogen enter fuel cell, make hydrone and air molecule be the gaseous state that mixes after in humidifying device, directly contacting, collide with pure water, air, when hydrone enters fuel cell, be the air that reaches certain relative humidity.
2. before dry air or fuel hydrogen and pure water enter fuel cell, not directly contact in humidifying device, but can allow hydrone freely see through but the film that do not allow gas molecule see through is separated by one deck, when film flows through dry air or hydrogen on one side, and the film another side is when flowing through pure water, hydrone will see through the film another side on one side from film automatically, makes air molecule mix the air of the relative humidity that reaches certain with hydrone.This film can be a proton exchange membrane, as Nafion film of E.I.Du Pont Company etc.
3. a kind of utilization of Shenli Science and Technology Co Ltd, Shanghai invention enters the humidifying device (number of patent application: 02217654.3) that dry air and the humid air that goes out fuel cell before the fuel cell carry out the water exchange, this humidifying device is made of a rotation inner bag, the interior absorbent material of filling, when dry air passes through, the hydrone on packing material surface in the inner bag is taken away, and humid air and water are by packing material surface in inner bag adsorbed water molecule again.
But present technical scheme becomes after the hydrogen that fuel cell pack is carried passes through humidification with air and directly enters fuel cell pack generation electrochemical reaction behind the humid air that reaches certain relative humidity and temperature, the hydrogen following technological deficiency is arranged:
1. in general, above-mentioned humidifying device all is to design for the condition of work of fuel cell when the nominal operation state.When hydrogen of carrying to fuel cell pack and the bigger variation of air mass flow generation, such as hour at flow, caused humidification easily, the hydrogen or the easy condensation of air of crossing humidification go out a small amount of aqueous water, and this aqueous water will be brought into respectively in fuel cell hydrogen flow guide groove, the air conducting groove by wet hydrogen, humid air.Cause the water blockoff of guiding gutter.In certain monocell in the hydrogen flow guide groove in water blockoff or the air conducting groove water blockoff can cause this monocell to be in the starvation of fuel hydrogen or air supply deficiency, this monocell performance will sharply descend, and can cause this electrode antipole when serious and burn.
2. the design of above-mentioned humidifying device generally all is under the nominal operation state by fuel cell, and under the nominal operation temperature, specified hydrogen, air mass flow can reach the hydrogen of design object, the control of relative air humidity after by humidifying device.But when ambient temperature changes and outside air relative humidity variations greatly the time, hydrogen, the relative air humidity that the passes through above-mentioned humidifying device controlling value that will depart from objectives, promptly wet excessively or overdrying causes the fuel cell operation unstable properties.
