POLYMER ELECTROLYTE MEMBRANE FUEL CELL WITH BIPOLAR PLATE HAVING MOLDED POLYMER PROJECTIONS |
摘要 |
A polymer electrolyte membrane fuel cell comprised of polymer electrolyte membranes, gas diffusion electrodes that sandwich the membranes, and bipolar plates operating as gas separation plates and current collectors with fuel/oxidizing agent supply and discharge passages provided by projections on both of its surfaces. A bipolar plate is employed which comprises projections on the bipolar plate of a melt-processible polymer having good fluidity and a coating on the surfaces of the bipolar plate comprising metal, metal nitride or metal carbide. |
