ABSTRACT:
A separator for use in a solid polymer electrolyte fuel cell, including a membrane/electrode assembly including a fuel electrode and an oxidant electrode disposed on either side of a solid polymer electrolyte membrane; a first separator superposed against a surface of the oxidant electrode forming an oxidant gas flow passage; and a second separator superposed against a surface of the fuel electrode forming a fuel gas flow passage. The first separator and the second separator are composed of rectangular thin metal plates, with outer peripheral edges of the first separator and the second separator each bending inclined towards a secondary face thereof on an opposite side of a primary face thereof that is superposed against the membrane/electrode assembly, thereby integrally forming a reinforcing rib.
