摘要
BaxCe0.8Y0.2O3-α(x=1.03,1,0.98) solid electrolyte samples show a single phase of orthorhombic perovskite of BaCeO3. The oxide ion conduction and transport number were detected in the temperature of 600~1000℃by electrochemical oxygen permeation (oxygen pumping), and compared with the results from the oxygen concentration cell. The relation between the ingredient of Ba and oxide ion conduction was also researched. It was found that these electrolytes exhibited the mixed oxide ionic and electronic hole conduction under the experimental temperature and oxygen gas. The oxide ion transport numbers are 0.1~0.6, which are close to the results of the oxygen concentration cell. They increase as the decrease of Ba content in the samples.
