<P>PROBLEM TO BE SOLVED: To restrain generation of deformation such as a curve on a GDL peripheral edge section while securing a reaction area related to a GDL power generation operation in order to restrain generation of poor molding, in a sealing structure for a fuel cell wherein a gasket is integrated with the GDL peripheral edge section according to a rubber impregnated structure. <P>SOLUTION: The sealing structure has a GDL (gas diffusion layer) made from a porous body, and a gasket integrally molded on the GDL peripheral edge section. The GDL has a rubber impregnated section, and an impregnation stop section. The gasket has a gasket body section with a thickness dimension greater than a thickness dimension of the GDL excluding the section impregnated to the GDL, and has an overlapping section flatly overlapped with the GDL in a body. The rubber impregnated section of the GDL has an inner section not flatly overlapped with the gasket between an outer section where the overlapping section of the gasket is flatly overlapped and the impregnation stop section. <P>COPYRIGHT: (C)2011,JPO&INPIT |
