A separator ( 4 ) for a fuel cell ( 1 a) is provided which allows effective use of heat generated in proximity to an electrolytic membrane ( 2 ) in order to melt frozen water in the gas diffusion electrodes ( 3 a, 3 b) of the fuel cell ( 1 a). The separator ( 4 ) is provided with a plurality of projections ( 11 ) between which a gas flow passage ( 7 a, 7 b) on the surface of the separator ( 4 ) is formed and which make contact with the gas diffusion electrodes ( 3 a, 3 b). The coefficient of thermal conductivity of the projection ( 11 ) is smaller than the coefficient of thermal conductivity of other sections of the separator ( 4 ). |
