Study on the Perovskite-type Oxide Cathodes in Proton-conducting SOFC
Published online by Cambridge University Press: 26 February 2011
Abstract
The cathode performances of perovskite-type oxide electrodes were investigated in the H2-O2 fuel cell with proton-conducting electrolyte. Among the perovskite-type oxides tested in the present study, La1-xSrxFeO3(LSFO) showed the best cathode performance. The cathode performances of LSFO depended on the Sr content and the heat-treatment temperature prior to electrochemical measurements. The cathode reactions of both LSFO and Pt electrodes are discussed briefly based on the cathode overpotentials measured as a function of oxygen partial pressure. Finally, the structure and the electrical conductivity of the proton-conducting ceramic film fabricated on LSFO electrode substrate are presented.
