From the viewpoint of the electrode for solid oxide fuel cells, Gd{sub 1{minus}x}A{sub x}MnO{sub 3} (A = Ca and Sr) was studied for its electrical conductivity, cathodic polarization, and reactivity with yttria-stabilized zirconia [8 mole percent (m/o)] Y{sub 2}O{sub 3} doped zirconia. Although cathodic activity and electrical conductivity are similar to the La{sub 1{minus}x}A{sub x}MnO{sub 3} system, stability with yttria-stabilized zirconia electrolyte is far superior. Gd{sub 1{minus}x}A{sub x}MnO{sub 3} (x {le} 0.5), for example, yields no reaction product with yttria-stabilized zirconia at high temperature, which is very attractive for practical applications in a solid oxide fuel cell.
