The Fe, Ni-BCY20 and Fe-Ni catalysts were used as the materials for anode 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 was employed as the electrolyte(thickness 500 µm) and a Pt was applied as the cathode. The cell was operated at 600°C. The maximum power density of the cell with the Fe9-Ni1 anode that has 9/1 molar ratio of Fe to Ni was 46.4 mW cm−2 at 80 mA cm−2. The Fe9-Ni1 anode showed remarkable improvement of cell performance in comparison with the Fe anode that we reported before.
