| 摘要 |
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 fuel electrode forming a fuel gas flow passage; and a second separator superposed against a surface of the oxidant electrode forming an oxidant gas flow passage. A single type metal separator is produced by subjecting a rectangular thin metal plate to punching and drawing by means of pressing to produce upper and lower through-holes of a pair of opposite sides, as well as forming a plurality of recesses extending substantially parallel to connect the upper through hole of a first opposing side with the lower through-hole of an other opposing side. The single type metal separator, when flipped front to back, can be used as both the first and second separators.
