| 摘 要： | In recent years, mixed-conducting oxides, in which both protonic and electronic charge carriers exist, have received increasing attentions1. Ceramic membranes made of such materials are semipermeable to hydrogen at elevated temperatures. In the early 1980s, Iwahara et al. first reported protonic conduction in SrCeO3-based materials2. Later, BaCeO3 system was extensively studied because of its higher conductivities. However, the electronic conductivity of rare earth doped-BaCeO3 ceramic…
