Description
Technical field
The present invention relates to fuel cell technology, particularly related to a proton exchanging film fuel battery half-cell assembly and a manufacture method thereof.
Background technology
The existing world today along with the continuous lifting of science and technology and rapid economic development and people's living standard, more and more can't satisfy the demand of human daily production, life for traditional fossil energy (as oil, natural gas etc.).Traditional energy mostly is non-renewable energy resources, and reserves are limited, can be consumed totally, and this type of energy can cause serious global problem of environmental pollution sooner or later.For the sustainable development of the earth and human society, a kind of reproducible clean energy resource all is being devoted to search out in countries in the world.Scientists is consistent at present thinks that " Hydrogen Energy " is one of following effective clean energy resource that substitutes traditional energies such as gasoline, diesel oil; But the words that hydrogen directly utilizes, energy conversion efficiency ground is low, so being applied to of fuel cell for a kind of effective way, wherein attach most importance to Proton Exchange Membrane Fuel Cells especially, because it is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that a kind of chemical energy that directly will be stored in fuel (as hydrogen) and the oxidant (as air) is converted into electric energy efficient and environmentally friendlyly, be acknowledged as following cleaning electrical source of power because it possesses these advantages, and all had application widely in fields such as portable power supply, stand-by power supply, automobile, Aero-Space.
Usually, the tradition pem fuel cell stack is made up of many groups monocell, one group of monocell is made up of membrane electrode (MEA), minus plate, positive plate, seal, as shown in Figure 1: hydrogen flow field seal 1, positive plate 2, water flow field seal 3, minus plate 4, air flow field seal 5, membrane electrode 6.The minus plate of the positive plate of monocell and another group monocell connects to form one group of fuel battery double plates, between two pole plates seal configuration is installed, then place a slice membrane electrode between per two groups of bipolar plates, seal configuration also is installed between bipolar plates and the membrane electrode, seal configuration plays the fluid pill chamber in battery, prevent the effect of gas leakage.Require to add behind the monocell of series connection some annex such as end plate again according to the difference of load utilization voltage and form a fuel cell pack.So as can be seen, the parts that fuel cell pile assembling process preface will repeat nearly more than 6, cause the assembling process complexity, occur neglected loading, misloading phenomenon easily.
Proton Exchange Membrane Fuel Cells is in when work, and it is inner, and following course of reaction takes place: hydrogen and air spread in diffusion layer, when reacting gas arrives Catalytic Layer, adsorbed by catalyst in Catalytic Layer and electrocatalytic reaction takes place; Hydrogen is delivered to cathode side at hydrogen proton that anode reaction generates in by proton exchange membrane, and electronics arrives negative electrode through external circuit, is combined into water with airborne oxygen molecule at cathode side Catalytic Layer internal reaction, emits heat simultaneously.Cooling water is taken liberated heat out of fuel battery inside.Can understand from its course of reaction, the electrochemical reaction of fuel cell is the course of reaction of a multithread body in conjunction with electro-catalysis.Hydrogen is a kind of gas that very easily leaks, and can cause dangerous situations such as burning and blast in case take place to leak or with air mutual string takes place.Cooling water and gas generation leakage or mutual string can influence the pile performance and cause situation generations such as water logging.So the sealing technology of fuel cell pack requires just to seem most important.
Shenli Science and Technology Co Ltd, Shanghai discloses a kind of sealing way of cell of fuel cell in patent ZL01105975, the employing independently seal washer of moulding in advance is embedded into the way that forms hermetically-sealed construction between fuel battery pole board seal groove and the membrane electrode, needs many steps sealing gasket is embedded the step of seal groove.This method is fit to produce in batches the gasket seal that fuel cell is used, but its method fails to realize with directly moulding on pole plate of sealing ring, and the pole plate that uses this method to form is very complicated in assembling, must superpose successively with the order of a slice minus plate, a slice positive plate, a slice membrane electrode, and the sealing ring that needs between each unit to place independent moulding seals.Such method is complex process not only, and workload is big, and the pile demolition and maintenance are also quite complicated; And because sealing ring is independently originally, be respectively independent sealed and pole plate assembling front and back effect schematic diagram as Fig. 2-A, 2-B, realize sealing by thrust fully after the assembling, the contact-making surface 8 between seal and the pole plate may have the slit, air-tightness is undesirable, causes gas leakage easily.In addition, the making of seal washer needs mold developing, early development cost height.
Honda Motor Co. mentions a kind of directly method of sealant on bipolar plates in ZL02813619, ZL02813979, ZL200610075875, by compression method fuel cell module is all bonded together at last.The fuel cell module that obtains by this method is not real bipolar plates before assembling, more is not half-cell, only is unipolar plate.The way of coating is to adopt in starting point to intersect the way processing that prolongs, need to strengthen the dividing plate area of gluing, cause the area waste, the fuel cell pack by the bonding composition of this technology can't the repeated removal maintenance, and when assembling is complicated, the situation of neglected loading or misloading may occur.
China Mining University has mentioned a kind of preparation method of solid oxide fuel cell cathode load type half-cell in patent ZL200610080597.0.The preparation method of the solid oxide fuel cell cathode load type half-cell of this disclosure of the Invention belongs to the technical field of fuel battery negative pole composite preparation process, proposition is feedstock production LSM layer and LSM/YSZ composite bed with the zirconia YSZ nano-powder and the manganese strontium acid lanthanum micro-powder LSM of stabilized with yttrium oxide, with the two formation base film that is combined with each other, carry out presintering then and obtain cathode substrate, adopt painting method or method for printing screen to prepare the YSZ film again, carry out sintering at last and make cell cathode load type half, the half-cell of this invention does not comprise sealing, structures such as gas distribution also need many different parts in the pile assembling process.
