The process for preparing it includes such steps as filling graphite creep in upper and lower dies, putting metal sheet in the graphic creep, and pressing, or filling graphite creep in upper and lower dies, pressing and coating polypyrrole or polyphenylamine layer on its surface. Its advantages include high corrosion resistance, high weight, good electric conductivity and low cost.
Description
Technical field
The present invention relates to a kind of composite-layer bipolar plate and manufacture method thereof of polymer-membrane fuel battery.Belong to hydrogen-oxygen, direct methanol fuel cell bipolar plate material and manufacturing technology.
Background technology
The bipolar plates of polymer-membrane fuel battery normally adopts three high graphite or metal to process.Three high graphite bi-polar plates make its gauge bigger because of guaranteeing enough mechanical strengths, and electric conductivity is not ideal enough, and the volumetric power density of battery pile is lower.The good conductivity of metal double polar plates short-term, but perishable, cause long-term electric conductivity to descend, must be through surface treatment, in addition, the weight of metal double polar plates is bigger, and the weight power density of battery pile is lower.In order to overcome the deficiency of above-mentioned bipolar plates, developed multiple bipolar plate material abroad.Resin impregnation graphite is an important class, although concrete material, proportioning, moulding and processing method are had nothing in common with each other.Resin impregnation has improved the fragility of admant China ink, can make the thinner easier processing of flow-field plate, and may adopt forming method efficiently such as mold pressing, mould notes.But this class technology generally can make the resistance of resin increase and the resin carbonation process in material yielding etc.The patent proposition employing graphite powder or other material with carbon element and the compound system bipolar plates of polymeric material that have are perhaps modified graphite bi-polar plate with conducting polymer, thereby improve the electric conductivity of graphite bi-polar plate.But processing mode is complicated, and cost is higher, and electric conductivity is also not ideal enough.Flexible graphite has the required multinomial excellent characteristic of bipolar plates, but its air-tightness is relatively poor.Therefore have that to propose flexible graphite in the patent compound with resin or metallic plate, but still there are the problem of meeting increase resistance in general and resin compounded.
Summary of the invention
The object of the present invention is to provide a kind of composite-layer bipolar plate and manufacture method thereof of polymer-membrane fuel battery.This fuel battery double plates is corrosion-resistant, in light weight, conduct electricity very well, low cost of manufacture.
For achieving the above object, the present invention is implemented by following proposal.Adopt the fuel cell composite-layer bipolar plate of graphite worm and sheet metal and polypyrrole or the body plan of polyaniline compound conducting polymer, it is characterized in that: the overall structure of bipolar plates is made of graphite worm, at its outer surface is polypyrrole or polyaniline rete, blending polypyrrole or polyaniline network layer in the middle of wooden partition graphite worm layer, or at wooden partition graphite worm layer therebetween adhesion metal thin plate.
The method of making above-mentioned composite-layer bipolar plate is to adopt die pressing, its step is to fill up graphite worm in upper and lower mould, and at the middle sheet metal of placing of graphite worm, pressure forming then, perhaps in upper and lower mould, fill up graphite worm, pressure forming then, synthesize polypyrrole or polyaniline rete in polar board surface coating or electricity after the moulding, it is characterized in that:, in its internal void of wooden partition graphite worm, adopt electrosynthesis to make polypyrrole or layer/polyaniline conductive polymer network layer with 10～80MPa forming under the pressure.
Above-mentioned sheet metal is surface treated corrosion resistant plate or titanium plate, and their thickness is 0.1～0.3mm.
Above-mentioned polypyrrole or polyaniline film layer thickness are 0.01～0.1mm.
Composite-layer bipolar plate of the present invention is corrosion-resistant, in light weight, conduct electricity very well, low cost of manufacture.
