Description
Technical field
The utility model belongs to Proton Exchange Membrane Fuel Cells technical field, specifically a kind of hydrogen power supply based on metal double polar plates.
Background technology
Proton Exchange Membrane Fuel Cells (PEMFC) is directly converted into electric energy by the chemical energy in fuel by electrochemical reaction mode, has the advantage of high-efficiency environment friendly.The operation principle of PEMFC is: fuel gas and oxygen arrive respectively anode and the negative electrode of battery by the gas passage in bipolar plates, arrives Catalytic Layer by the diffusion layer on membrane electrode assembly (MEA).In the anode-side of film, hydrogen is dissociated into proton hydrate and electronics on anode catalyst surface, and proton hydrate is by the sulfonic group (SO in proton exchange membrane
3h) transmit and arrive negative electrode, electronics flows through load by external circuit and arrives negative electrode.At the catalyst surface of negative electrode, oxygen molecule, in conjunction with the proton hydrate and the electronics that pass over from anode, generates hydrone.In this process, proton will carry hydrone and be delivered to negative electrode from anode, and negative electrode also generates water, and water is got rid of from negative electrode.Because the conduction of proton will rely on water, the wetness degree of proton membrane has very large impact to its conductivity, so need to carry out humidification to reacting gas.The single-unit operating voltage of fuel cell is generally 0.6 ~ 0.7V, obtain useful voltage and high power, the series connection of more piece monocell must be formed to pile, meets high-power user demand.The proton exchange film fuel cell electric piling efficiency that competence exertion is good is under certain conditions to realize reliable work, and these conditions comprise: control temperature 80
oc following (cooling system), keep proton exchange membrane all the time in wetting state (humidification system), supply with sufficient air (or oxygen) and hydrogen (air supply system and hydrogen feed system).The fuel using due to PEMFC work is flammable explosive gas (hydrogen), for preventing contingency, also must be equipped with warning system and fire extinguishing system.Meanwhile, for controlling the input and output of PEMFC, and each system coordination work, the also control system of necessary Erecting and improving.Therefore, all these back-up systems are that PEMFC is efficient, the necessary condition of steady operation.
Chinese invention patent CN200610121862.5 announced a kind of can be according to the fuel cell of loaded work piece, it need to carry out humidification to air, uses air pump simultaneously, weight and the cost of fuel cell system increase greatly.Chinese invention patent CN86100407 has announced a kind of fuel cell power system, comprises the fuel cell unit that hydrocarbon fuel is converted into the fuel regulator of hydrogen-rich combustion gas and combustion gas is converted into electric energy.This power-supply system is furnished with the large-scale subsidiary engines such as reforming hydrogen production device, heat exchanger, air blast, coolant circulating pipeline, and system is very complicated.Chinese invention patent CN200810204755.8 has announced the standby power system of a kind of fuel cell and energy-storage battery composition, and this system comprises fuel cell and large-scale energy-storage battery, causes power supply control complexity, system cost higher, is difficult for mobile application.
In a word, at present all large (energy density less than 250W.h/L, specific energy less than 300W.h/kg) of fuel cell system volume and weight, system configuration complexity, is difficult to portable use.
Connect two adjacent cell partition and be called bipolar plates, bipolar plates not only need to electrode in pile reactant is provided and between adjacent two electrodes conduction current, but also undertaking the effect of discharging battery and generate water and reaction heat.

At present, bipolar plates mainly contains carbon/graphite bi-polar plate, composite dual-electrode plates and metal double polar plates three types.Metal double polar plates, because having good conduction, thermal conduction characteristic, pliability and workability, comes into one's own and pays close attention to.Compare with composite material with graphite, there is not air-tightness problem in metal, even and if metallic plate is made the very thin good mechanical strength that also can ensure, thereby can greatly reduce pile volume and weight, simultaneously because metal has higher thermal conductivity, pile internal temperature gradient is little, is also conducive to improve the uniformity of pile internal temperature.Therefore utilizing for example corrosion resistant plate punch forming of sheet metal to prepare bipolar plates, is research in recent years focus.
The for example open fuel cell metal double polar plates of Chinese patent application 201110236288.9, be provided with three chamber common-use tunnels in cathode and anode unipolar plate both sides, middle part is established DC fields runner, distributes runner and is imported and exported runner, DC fields runner is made up of parallel projection and groove, distributes runner section to be made up of the strong point of the channelizing island of arranging by rule and reverse projection.
Chinese patent application 200710140168.2 discloses a kind of fuel cell metal double polar plates, on plate-shape metal substrate, be prepared with passivated metal layer and layer of precious metal, metal double polar plates has the jog at least forming in the region of the electrode towards septum electrode assembly, two surfaces of metal double polar plates have respectively with the contact surface of described electrode contact and not with the noncontact surface of described electrode contact.
Chinese patent application 201010288870.5 discloses a kind of stamping forming fuel battery metal double polar plate, comprises the first metallic plate and the second metallic plate, and two plate reverse side pass through laser welding.The first metallic plate front arranges sealing platform area, and two plates arrange interrupted corner guiding gutter between flow field runner and each gas inlet and outlet, and strip groove is established in two plate cooling water outlet and inlet neighboring areas.
The disclosed thin metal dual-pole board of proton exchange film fuel battery of Chinese patent literature CN1996647, between yin, yang pole plate, omit coolant flow field, reduced package thickness, cathode and anode flow field has only utilized a side runner, cathode flow field both as reaction gas runner also as cold gas runner.
Meanwhile, due to the internal environment of Proton Exchange Membrane Fuel Cells in humidity, acidity and higher temperature, therefore metal double polar plates must improve its surface conductivity and corrosion resistance by process for modifying surface.The normal method adopting comprises PVD, CVD, plating and coating processing at present.In a word, up to the present also do not have a kind of metal double polar plates to be able to large-scale application, performance, life-span and the cost of metal double-polar-plate fuel cell galvanic also do not reach commercialization index.For this reason, be badly in need of exploitation satisfactory electrical conductivity, high corrosion-resistant and fuel battery metal double polar plate cheaply.
