PROBLEM TO BE SOLVED: To provide an end plate with electric improved insulation. SOLUTION: For end plates 3, 4 used for a fuel cell, metal plates 31, 41 formed of aluminum with a preset thickness and sufficient strength are coated with insulating film sheet structures 32, 42 formed of fluorine based resin including polytertrafluoroethylene(PTEE) and polyphenylenesulfide(PPS). Coating with the insulating films is applied at least to an area opposed to a cell stack of the plate and to an area opposed to a manifold and so no pin hole is formed in the insulating layers of the end plates 3, 4, resulating in excellent electric insulation. |
