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℃.

结果表明，在600~1000℃温度范围内、湿润氢气和湿润空气气氛中，该系列材料的电导率随温度和钡离子含量的变化均与以该系列材料为固体电解质的氢－空气燃料电池性能随温度和钡离子含量变化的次序一致，即：非化学计量组成材料BaCe0.8Ho0.2O(下标 3-α)(x=1.03， 0.97)具有较化学计量组成材料BaCe0.8Ho0.2O(下标 3-α)(x=1)高的电导率和氢－空气燃料电池输出功率密度，其中BaCe0.8Ho0.2O(下标 3-α)有最高的电导率（1000℃时、在湿润的氢气气氛中：2.10×10^(-2)Scm^(-1)；在湿润的空气气氛中：3.46×l0^(-2)Scm^(-1)）和最大的氢－空气燃料电池输出功率密度（1000℃时：122mWcm^(-2)）。
