Abstract
The present invention belongs to a technology for making fuel batteries, which comprises the steps that a mold is made according to a bipolar plate and a flow field which are suitable for technological requirements; Temperature-resisting resin is selected and is formed by an injection molding machine through one time, and then, the resin is squeezed and pressed under high pressure into a plastic bipolar plate with high strength, corrosion resistance and working temperature resistance; the technology of plating metal on plastic surfaces is adopted to plate a layer of corrosion-resistant alloys with the function of electric conduction on the surface of the bipolar plate formed by one time. The present invention has the advantages of simple manufacture and low cost. The present invention can reduce the cost of fuel batteries, guarantee the stability in the running process and maintain the stable and reliable work of fuel battery galvanic piles, and no chemical group is released.
Description
Technical field the invention belongs to the energy, technical field of power generation, particularly manufacture technology of fuel cell.
Background technology
Patent (the Chinese patent application of Dalian Inst of Chemicophysics, Chinese Academy of Sciences's application, application number is 98114178) bipolar plates of a proton exchanging film fuel battery disclosed, constitute by three layers of metal sheet, the centre is the demarcation strip of the airtight liquid of electrical conduction current, and both sides are equipped with the baffler of tape shape groove respectively.This technology is to make cell bipolar plate with stacked conducting plate, and its shortcoming is too complicated, deals with improperly and can produce electrochemical corrosion, increases the internal resistance of cell.
Patent (the Chinese patent application of Hitachi Chemical Co., Ltd.'s application, application number is 85104873) a kind of fuel cell of making is disclosed with the method for ditch partition wall is arranged, its method comprise the following steps: lamination a plurality of flooded water and (or) expanded graphite plate of organic solvent. make up a plurality of dippings cross or do not flood water and (or) expanded graphite plate of organic solvent, the preforming laminated plate. the laminated plate after the dry preforming, the dried laminated plate of extrusion forming.With the product that this method is made, its shortcoming is the requirement that conductivity is difficult to meet fuel cell.In addition, in the use of graphite level, constantly ooze out chemical group, polluted the water of pile inside, thereby reduce the pile performance, can make the pile short circuit when serious.
Summary of the invention
The objective of the invention is for overcoming the weak point of prior art, a kind of making process of two plates of proton exchange film fuel cell is proposed, make its have make simple and cheap, can reduce the fuel cell cost, and guarantee in running stable, do not discharge chemical group, keep fuel cell pile working stability, reliable advantage.
A kind of making process of two plates of proton exchange film fuel cell that the present invention proposes may further comprise the steps:
The second,, and make mould thus according to the bipolar plates and the flow field that are fit to technological requirement;
The second, choose the heatproof resin, use the injection molding machine one-shot forming, high-pressure extrusion is made anti-working temperature 50-130 ℃ plastics bipolar plates;
Three, adopt frosting lining smithcraft, with the corrosion resistant alloy of one-shot forming bipolar plate surfaces lining one layer thickness less than 0.2 millimeter electric action.
Said heatproof resin can adopt a kind of of polyethylene, polyvinyl chloride, Merlon and ABS resin.
That said corrosion resistant alloy can be is Ni-based, titanium base, gold a kind of.
Characteristics of the present invention:
The present invention has overcome the gas leakage problem of carbon bipolar plate fully owing to adopt high-temperature resistance plastice to make bipolar plates with injection moulding process; Since carried out the flow field when making bipolar plates on its surface, can economic production.Because the conductivity of plastics is still not ideal enough, so play electric action at its surperficial lining metal level, the bipolar plates of making is like this wanted considerably cheaper than the bipolar plates of directly making with thin metal stamping.
Embodiment
A kind of making process of two plates of proton exchange film fuel cell embodiment that the present invention proposes may further comprise the steps:
1) preparation is fit to the flow of hydrogen and oxygen and water, design single channel or multichannel flow field bipolar plates,, and make mould thus;
2) become plastics bipolar plates blank with ABS resin via the injection molding machine high-pressure extrusion, it is two-sided all the gas flowfield groove;
3), promptly make the bipolar plates of used in proton exchange membrane fuel cell at plastics bipolar plate surfaces lining Ni base alloy.
Claims (3)
1, a kind of making process of two plates of proton exchange film fuel cell may further comprise the steps:
The first,, and make mould thus according to the bipolar plates and the flow field that are fit to technological requirement;
The second, choose the heatproof resin, use the injection molding machine one-shot forming, high-pressure extrusion is made anti-working temperature 50-130 ℃ plastics bipolar plates;
Three, adopt frosting lining smithcraft, with the corrosion resistant alloy of one-shot forming bipolar plate surfaces lining one layer thickness less than 0.2 millimeter electric action.
2, making process of two plates of proton exchange film fuel cell as claimed in claim 1 is characterized in that, said heatproof resin adopts a kind of of polyethylene, polyvinyl chloride, Merlon and ABS resin.
3, making process of two plates of proton exchange film fuel cell as claimed in claim 1 is characterized in that, said corrosion resistant alloy is a kind of of Ni-based, titanium base, gold.
