Abstract:
1. A separator for a polymer electrolyte fuel cell having unit cells arranged in a flat manner, said separator provided on a fuel feed side or an oxygen feed side, said separator comprising: a separator member coupled body having a metal plate as a base body, and formed by integrally coupling a plurality of separator members each having through holes for feeding fuel to an electrolyte of the fuel cell, said through holes arranged so as to correspond to the unit cell and to be perpendicular to a surface of said base body, and frame coupled bodies each made of an insulating material, each having openings for fuel feeding or oxygen feeding corresponding to the respective separator members, and each formed by integrally coupling a plurality of frame members that give insulation between the unit cells, wherein said frame coupled bodies, making a pair, sandwich said separator member coupled body from both sides of the separator member, and each frame member of one of the frame coupled bodies on the front and back of said separator member coupled body is configured to accommodate a membrane electrode assembly of the fuel cell into said respective volume of an opening of said each frame member.
