A gasket device for a fuel cell stack according to the present invention can ensure all main properties of a gasket for a fuel cell stack by integrally molding gaskets composed of different materials on an anode separator (or anode gas diffusion layer) and a cathode separator (or cathode gas diffusion layer) via an injection molding method and thereby solving the problems of a cell composed of a single material and having an integrated structure such as sealing stability problems at low temperature and lack of long-term usage stability. Also, an anode gasket and a cathode gasket composed of different materials can be used to control the molding and crosslinking conditions of each of the gaskets independently. In addition, the anode gasket and the cathode gasket are discerned and managed easily by only looking at the appearance of the stack because of different colors. |
