摘要
用高温固相反应法制备了非化学计量性固体电解质Ba0 .98Ce0 .9Y0 .1O3 -α,分别用氢浓差电池及氧浓差电池方法研究了在 60 0～ 10 0 0℃范围Ba0 .98Ce0 .9Y0 .1O3 -α的离子导电特性。结果表明 ,Ba0 .98Ce0 .9Y0 .1O3 -α固体电解质在氢气气氛中几乎为纯质子导体 。
Ba 0.98 Ce 0.9 Y 0.1 O 3-α solid electrolyte has been prepared by high temperature solid state reaction. Its ion conducting characteristics have been investigated by means of hydrogen and oxygen concentration cells between 600℃ and 1000℃. It was found that the solid electrolyte exhibited almost a pure protonic conduction under hydrogen atmosphere, where as it was a mixed conductor of oxide ion and electron hole.
