<P>PROBLEM TO BE SOLVED: To provide a fuel cell of less weight and smaller size by, relating to a separator formed with a metal plate, allowing the plate thickness of an inside gas flow channel to be thinner than the plate thickness of a gas seal that requires rigidity, and preventing increase in plate thickness of the entire separator as the plate thickness of the gas flow channel is equivalent to that of the gas seal part. <P>SOLUTION: A separator 1 is integrally molded from a metal plate. The plate thickness of a gas seal 35 at the periphery of it is so designed as not to be deformed by the reactive force of a compressed seal material 39 that is pressurized under an arbitrary load for preventing gas leakage. Gas communications 31 and 33 as well as a power generation channel 41 that are inside gas flow channels 24 are thinner than the plate thickness of the gas seal part 35. <P>COPYRIGHT: (C)2007,JPO&INPIT |
