| Abstract Scope |
Cobalt-containing oxides such as LSC and BSCF are well-known to exhibit a superior oxygen reduction reaction (ORR) activity at intermediate temperatures for IT-SOFC. Even though their perovskite-type structure having a large amount of highly mobile oxygen vacancies is definitely responsible for their cathode performance, the catalytic activity of cobalt element itself is not well understood. The focus of this study is then to clarify its catalytic activity at intermediate temperatures apart from the perovskite-type structure. To investigate the surface kinetics of cobalt-containing oxides, a pulse isotopic exchange technique is utilized. The role of cobalt element on ORR will be discussed with respect to the surface and electronic structures of oxides. |
