In order to achieve cost reduction for fuel cell stacks, gaskets (1 (2)) for a fuel cell are formed integrally by a rubber-like elastic material on the outer periphery of GLDs (3 (4)), which are interposed between separators (6 (7)) and an MEA (5), and are in intimate contact with the separators (6 (7)). On the surfaces of these gaskets (1 (2)) facing the separators (6 (7)), a gas introduction groove (1b) is formed extending such that manifold holes (1a (2a)) provided in an open condition in these gaskets (1 (2)) and a gas reaction region (10A) formed by the MEA (5) are linked to each other. This gas introduction groove (1b) can be formed at the same time as the forming of the gaskets (1 (2)) by a rubber-like elastic material, and a gas introduction groove need not be formed on the separator (6 (7)) side; therefore, costs can be reduced. |
