Abstract

The anodic performance of CeO2 doped with Mn and Fe was studied by using a Co-doped LaGaO3 -based oxide (LSGMC) electrolyte. The open-circuit potential approximate to the theoretical value (1.1 V) was exhibited on the cell using Ce(Mn,Fe)O2 oxide for the anode. A high maximum power density (0.622 W/cm2 at 1273 K) was attained by co-doping Mn and Fe into CeO2. After a few cycles of oxidation treatment at 1073 K, there was an increase in the maximum power density. Therefore, Mn- and Fe-doped CeO2 is a potential oxidation-tolerant oxide anode for solid oxide fuel cells (SOFCs) using an LSGMC-based electrolyte.
