Abstract

Anodic performance of oxide composites consisting of Ce(Mn,Fe)O ₂-La(Sr)Fe(Mn)O₃ was studied. The open circuit potential was close to the theoretical value for the cell using oxide composite of Ce(Mn,Fe)O₂-La(Sr)Fe(Mn)O₃. On the other hand, the maximum power density is much improved by mixing two oxides for anode and the highest power density is achieved on the cell using 12.5 wt% Ce(Mn,Fe)0₂ mixed with La(Sr)Fe(Mn)O₃ for anode at intermediate temperature. The maximum power density was 970 and 23 mW/cm² at 1273 and 773 K, respectively. On exposure of anode to air at 1073 K, the maximum power density returned to the almost original level after changing air to H₂. Therefore, this study reveals that the composite of doped CeO₂ and LaFeO₃ based perovskite is useful as an oxide anode for SOFC using LSGMC based electrolyte.
