Patent ID: 8153330

Claim:
A fuel cell separator stacked on an electrolyte electrode assembly in a stacking direction, said electrolyte electrode assembly including an anode, a cathode, and an electrolyte interposed between said anode and said cathode, the fuel cell separator comprising: a sandwiching section for sandwiching said electrolyte electrode assembly, a fuel gas channel for supplying a fuel gas along an electrode surface of said anode and an oxygen-containing gas channel for supplying an oxygen-containing gas along an electrode surface of said cathode being provided separately on said sandwiching section, said sandwiching section being configured such that the fuel gas and the oxygen-containing gas after consumption are discharged from an outer circumferential portion of said electrolyte electrode assembly; a bridge connected to said sandwiching section, a reactant gas supply channel for supplying the fuel gas to said fuel gas channel or supplying the oxygen-containing gas to said oxygen-containing gas channel being provided on said bridge; and a manifold connected to said bridge, a reactant gas supply passage for supplying the fuel gas or the oxygen-containing gas to said reactant gas supply channel extending through said manifold in the stacking direction, wherein a circumferential length R of said sandwiching section and a width H of said bridge satisfy a relationship of 0.03≦H/R≦0.20.
