Abstract
A solid electrolyte fuel cell has an air electrode, a fuel electrode and a solid electrolyte film disposed between the air electrode and the fuel electrode. The solid electrolyte film is formed of yttria-stabilized zirconia in which alumina is added, the concentration of the supplemented alumina at a surface layer section of the solid electrolyte film being larger than that at a center layer section of the solid electrolyte film.
