A fuel cell stack is provided which includes a gasket assembly interposed between the membrane-electrode assembly and an edge portion of the metal separator. In particular, the metal separator is formed of a first metal plate and a second metal plate welded to each other, and one or more curved portions, which are symmetrical to each other, formed around a welded portion of the first and second metal plates. The gasket assembly is then installed between a membrane-electrode assembly and the edge portion of the metal separator with the curved portion therebetween. |
