<P>PROBLEM TO BE SOLVED: To enable to alleviate a load difference between a power-generating part and a sealing part of the metal separator, prevent cracks of a metal plate as much as possible, and maintain a good sealing property. <P>SOLUTION: An oxidant gas flow channel 30 as a power generating part opposed to a cathode side electrode 26 and a flow channel sealing part 36a surrounding the oxidant gas flow channel 30 are provided on a face 14a of a first metal separator 14 constituting the fuel cell 10. A deforming part 40 more easily deformable than other parts when an outside load is imparted is provided between the oxidant gas flow channel 30 and the flow channel sealing part 36a, and at the same time, the deforming part 40 is provided with a bead-shaped part 42 extended along a length direction of the flow channel sealing part 36a. <P>COPYRIGHT: (C)2009,JPO&INPIT |
