摘要：

From the viewpoint of the electrode for solid oxide fuel cells, Gd(1-2)A(x)MnO(3) (A Ca and Sr) was studied for its electrical conductivity, cathodic polarization, and reactivity with yttria-stabilized zirconia [8 mole percent (m/o)] Y2O3 doped zirconia]. Although cathodic activity and electrical conductivity are similar to the La(1-x)A(x)MnO(2) system, stability with yttria-stabilized zirconia electrolyte is far superior. Gd(1-x)A(x)MnO(3) (x less than or equal to 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.
