SOLID ELECTROLYTE FUEL CELL ELEMENT

摘要

PROBLEM TO BE SOLVED: To inexpensively manufacture an SOFC which is excellent in a power generation characteristic even at a low temperature by forming an air electrode to show high activity even at a low temperature on a porous sintered body formed of an air electrode material, and forming electrolyte and a fuel electrode in the next place. SOLUTION: In an SOFC having structure that a support body composed of an electrode material mechanically supports a cell itself, it is formed as cell structure operable at a low temperature. An air electrode layer 2 composed of Pr(1- X) SrXMn(1- Y) CoYO3 (0.05<=X<=0.5 and 0<=Y<=0.6) is arranged on a porous support body 1 composed of La(1- X) SrXMnO3 (0.1<=X<=0.5), and a solid electrolyte layer 3 and a fuel electrode layer 4 are formed so as to be superposed on this air electrode layer. Since an air electrode support body is formed as a two-layer structure, an SOFC cell operable even at a low temperature can be inexpensively provided.
