An integral molding method of gasket of a fuel cell component member in which a gasket body is integrally molded with an outer peripheral portion of a membrane electrode assembly and a peripheral portion of an opening formed on the membrane electrode assembly by cross-linking molding using a mold having a heating means, the membrane electrode assembly comprising a proton exchange membrane, a gas diffusion layer integrally laminated on both sides of the proton exchange membrane via a catalyst carrier layer constituting an electrode. The mold has a cavity corresponding to a molding portion of the gasket body and a heat insulation zone corresponding to a power generating functional portion of the fuel cell component member, a not-cross-linked gasket material is filled in the cavity and the gasket material is molded by heat cross-linking molding using the heating means, whereby a heat generated by molding is prevented from being transmitted to the power generating functional portion by the heat insulation zone. The heat insulation zone is constructed with a recessed portion formed on the mold corresponding to the power generating functional portion, and an inner wall of the recessed portion is attached with a heat insulation material. |
