Claim 13:
14. A solid oxide fuel cell comprising:
a metal support cell having an anode layer containing nickel metal, an electrolyte layer and a cathode layer stacked on a metal support part,
the metal support part being formed of a porous metal and interposed between the anode layer and a flow passage portion through which an anode gas flows such that an entirety of the metal support part is provided between the anode layer and the flow passage portion, the porous metal being made of a corrosion resistant metal material,
the anode layer having three-phase boundaries defined by the nickel metal, electrolytes and pores,
the anode layer including conduction paths of the nickel that connect the electrolyte layer to the metal support part,
the conduction paths of the nickel being thinner than conduction paths formed by oxidization of the nickel, and the conduction paths of the nickel extending throughout the anode layer to a surface of the electrolyte to connect the electrolyte layer to the metal support part, and
the flow passage portion, the metal support part, and the anode layer being sequentially stacked such that the flow passage portion and the anode layer are in contact with opposite surfaces of the metal support part.
