TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The single thermoplastic resin is polyethylene, polypropylene, polybutylene, polyvinyl chloride, polystyrene, polyamide, polycarbonate, poly(meth) methyl acrylate, polyformaldehyde, polyphenyl ether, polyphenylene sulfide, polysulfone, polyether sulfone or fluorine resin. The different specifications are different molecular weights or polymerization, different molecular structures, different melting indexes, different melting points and/or different crystallization. The mass percentage of the single thermoplastic resin is 5-95 (preferably 40-60)% elastomer plastic. The conducting plastic further comprises conducting filler (5-80, preferably 50-60)%. The conducting filler is silica, carbon powder, graphite, chopped carbon fiber, carbon nanotube, carbon nanorod and carbon nanowire, preferably silica, carbon powder, graphite and chopped carbon fiber; the silica is 10-60 (preferably 30-40)% of the conducting filler; the carbon powder is 5-15 (preferably 8-10)% of the conducting filler; the graphite is 20-75 (preferably 40-50)% of the conducting filler; and the chopped carbon fiber is 10-30 (preferably 18-22)% of the conducting filler. The silica is with single structure or mixture of two or more of silica with different structures; the graphite is graphite with single particle size or mixture of graphite with different particle sizes; and the length of the chopped carbon fiber is 0.1-8 (preferably 3-5) mm. The thickness of the conducting plastic bipolar plate is 0.1-2 (preferably 0.8-1.2) mm; and the width of the conducting plastic bipolar plate is 600-1500 (preferably 900-1000) mm. Preferred Process: The method comprises mixing at least two polyethylene materials with different molecular weights, or mixing any two or three of low-density polyethylene, middle-density polyethylene and high-density polyethylene; or mixing at least two polypropylene materials with different molecular weights; or mixing any two or three of isotactic polypropylene, syndiotatic polypropylene and irregular polypropylene; or mixing at least two polyvinyl chlorides with different molecular weights; or mixing at least two polyvinyl chlorides with different melting indexes.
