ABSTRACT:
A solid electrolyte fuel cell having a long service life includes a power generating cell having a fuel electrode laminated on one surface of a solid electrolyte and an air electrode laminated on the other surface, an air electrode current collector laminated in contact with the air electrode of the power generating cell and formed of a porous silver material or a silver-coated porous metal material, a fuel electrode current collector laminated in contact with the fuel electrode of the power generating cell, an air electrode-side separator having a silver-plated layer formed on its surface on the side contacting the fuel electrode current collector, a fuel electrode-side separator laminated in contact with the fuel electrode current collector, and air supply passage provided by being connected with the air electrode-side separator and a fuel supply passage provided by being connected with the fuel electrode-side separator, wherein a silver vapor supply unit is provided in the air supply passage to thereby supply silver vapor-containing air to the air electrode current collector.
