PURPOSE: To improve the long time durability and reliability of a solid electrolytic fuel cell(SOFC), and reduce the manufacturing cost of a cell by a co- sintering method. CONSTITUTION: A lanthanum strontium manganate air electrode material is provided integrally with zirconia solid electrolyte material. It is made stabilization-treatment by scandia, and is blended with alumina. Solid solution of a manganese ion in the air electrode material into a grain boundary is restrained by preferential reaction to alumina existing in the grain boundary of the solid electrolytic material. |
