    摘要： End plates of a fuel cell are conventionally made by cutting metal plates. Therefore, they have problems in that it is difficult to reduce their cost, and they are inconveniently heavy, and they are likely to be corroded by supplied gases and cooling water since they contact such gases and water at inside surfaces of manifold holes of the metal end plates.
    According to the present invention, the end plates are made of a resin-dominant material, more preferably by injection-molding such material, so that it becomes possible to reduce the cost and weight of the end plates, and the corrosion resistance can be greatly improved by insert-molding the current collecting plates in such a manner that the end plate material extends into a manifold hole of each current collecting plate.

    摘要： A polymer electrolyte fuel cell comprises a cell stack comprising a plurality of membrane electrode assemblies and a plurality of conductive separator plates that are stacked alternately, each of the membrane electrode assemblies comprising a hydrogen-ion conductive polymer electrolyte membrane, and an anode and a cathode sandwiching the polymer electrolyte membrane. The conductive separator plate is formed of a molded plate comprising a carbon powder and a binder, the conductive separator plate having a main portion (16C) which is raised from a peripheral portion (17C) surrounding the main portion, the main portion being in contact with the anode or the cathode and being provided with a gas flow path (18) for supplying a fuel gas to the anode or a gas flow path for supplying an oxidant gas to the cathode.
