The results indicated that BaCe0.8Ho0.2O(subscript 3-α) sinters are of single-phase structures of orthorhombic perovskite. In the temperature range of 600~1000℃, the nonstoichiometric materials (x=1.03 and 0.97) have higher conductivities in wet hydrogen and wet air and better performances of hydrogen-air fuel cells than the stoichiometric one (x=1). In this series, BaCe0.8Ho0.2O(subscript 3-α) has the highest conductivities 2.10×10^(-2Scm^(-1) in wet hydrogen, 3.46×10^(-2) Scm^(-1) in wet air, at 1000℃ and the maximum power output density 122 mWcm^(-2 at 1000℃.
