<P>PROBLEM TO BE SOLVED: To prevent plastic deformation of a separator caused by the thermal cycle of a fuel cell and prevent breakage of a power generation cell. <P>SOLUTION: A plurality of power generation cells 5 and a plurality of separators having reaction gas passages 11, 12 are alternately stacked, a fuel gas manifold and an oxidant gas manifold communicating with the gas passages 11, 12 in the stacking direction are installed in the outer periphery part of a stack, and a load is applied to the stack in the stacking direction. The separator 8 is equipped with an interconnecting part 8a having the power generation cell 5 arranged in the central part, and a pair of arm parts 8b extended from the edge part of the interconnecting part 8a and connecting to the fuel gas manifold and the oxidant gas manifold at each end part 8c. Flexibility capable of displacing in the stacking direction is given to the arm part 8b, and the deformation of the arm part 8b is kept within an elastic range in a period of thermal cycle. <P>COPYRIGHT: (C)2008,JPO&INPIT |
