<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of prolonging lifetime of the battery by preventing deterioration and damage of a separator even if temperature increase of a fuel cell accompanying start and stop of the fuel cell and its process are repeated. <P>SOLUTION: The separator 10 is composed of a manifold which forms a communication hole of a reactive gas and cooling water at the time of lamination, a metal pressed plate 3 which has a gas passage for supplying uniformly the reactive gas supplied from the manifold to the electrochemical reaction face, a resin frame 9 which is laminated together with the metal pressed plate, and a seal material which integrates the resin frame and the metal pressed plate. The distance between a line connecting in lateral direction the passage end on the manifold side and the end face of the resin frame is 0.1 to 1.5 mm. The fuel cell uses this separator 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
