Method of producing an air electrode material for solid electrolyte type fuel cells
 A method of producing a self-supporting air electrode for a solid electrolyte fuel cell, including the steps of mixing lanthanum or a lanthanum compound, manganese or a manganese compound, and metal A or a compound thereof into a mixture, wherein A is selected from the group consisting of Sr, Ca, Mg, Y, Ce, Yb, Zn and Ba and pre-firing the mixture at a temperature of at least 1400.degree. C. to yield a synthesized product of La.sub.1-x A.sub.x MnO.sub.3 wherein 0<x .ltoreq.0.5 and forming the synthesized product into a green body and firing the green body to form a self-supporting air electrode body consisting of La.sub.1-x A.sub.x MnO.sub.3.
