The Fe, Ni-BaCe0.8Y0.2O3−δ, and Pt catalysts and Pt catalysts were used as the anodic materials of an intermediate-temperature Solid Oxide Fuel Cell (SOFC) for direct utilization of dimethylether (DME) gas fuel. A proton conducting oxide BaCe0.8Y0.2O3−δ (BCY20) was used as the electrolyte (thickness 500 µm) and a Pt was used as the cathode. The cell was operated at 600°C. The maximum power density of the cell with the Fe anodic catalyst was 36.4 mW cm−2 at 70 mA cm−2, while the maximum power density of the cell with a Ni-BCY20 and the Pt anode were 5.5 mW cm−2 at 10 mA cm−2 and 8.4 mW cm−2 at 20 mA cm−2, respectively. DME was mainly decomposed to H2, CO and CH4 by Fe anode. In this study, we investigated the process of anodic reactions with H2 and CO fuel.
