Abstract

Anodic performance and power generating properties of the cell using various oxide composites consisting of Mn, Fe co-doped Ce O₂ and perovskite oxide were investigated by using La_0.8 Sr_0.2 Ga_0.8 Mg_0.15 Co_0.05 O₃ electrolyte. It was found that the theoretical open circuit voltage and reasonably high power density were achieved on the cell using oxide composites consisting of Ce (Mn,Fe) O₂ -La (Sr) Fe (Mn) O₃ for anode. The maximum power density was achieved for values of ∼1.0, 0.3, and 0.05 W/ cm ² at 1273, 1073, and 873 K, respectively. Oxidation tolerance was also studied and it was found that the power density was slightly improved after exposure to reoxidation treatment. This study demonstrated that the cell using Ce O₂ and LaFe O₃ based oxide composite for anode is highly tolerant against reoxidation treatment. An increase in in the power density by reoxidation treatment was observed and this could be attributed to the improved contact of Ce (Mn,Fe) O₂ -La (Sr) Fe (Mn) O₃ composite powder.
