Patent ID: 7491460

Claim:
A fuel cell including a plurality of electrolyte electrode assemblies and separators sandwiching said electrolyte electrode assemblies, said electrolyte electrode assemblies each including an anode, a cathode, and an electrolyte interposed between said anode and said cathode, wherein each of said separators comprises: a plurality of sandwiching portions for sandwiching said electrolyte electrode assemblies and forming a plurality of fuel gas flow fields between one surface of said separator and respective anodes of said electrolyte electrode assemblies for supplying a fuel gas to said anodes and a plurality of oxygen-containing gas flow fields between the other surface of said separator and respective cathodes of said electrolyte electrode assemblies for supplying an oxygen-containing gas to said cathodes; a fuel gas supply unit formed at a central region of the separators and extending in a stacking direction of said separators for supplying unreacted fuel gas; a plurality of fuel gas supply channels diverged from said fuel gas supply unit, connected to said sandwiching portions, and communicated with said fuel gas flow fields, and wherein said fuel cell comprises a tightening load applying mechanism, and a load applied in the stacking direction to a position near said fuel gas supply unit by said tightening load applying mechanism is larger than a load applied in the stacking direction to said sandwiching portions by said tightening load applying mechanism.
