摘要：

Electrical conduction in sintered oxides based on calcium, strontium or barium zirconate at high temperature was investigated electrochemically. When Zr in MZrO3 (M = Ca, Sr or Ba) was partially replaced by trivalent element such as In, Sc, Y, etc., the resultant solid solutions exhibited protonic conduction under hydrogen-containing atmosphere at elevated temperatures. In general, the protonic conductivities of BaZrO3- and SrZrO3-based ceramics were higher than those of CaZrO3-based one although the values were low compared to those of SrCeO3 or BaCeO3-based ceramics. Clear isotope effects in IR spectrum and conductivity were observed between protonated and deuteronated SrZr0.95Y0.0503-alpha.
