    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.
