Development of the Fe-Ni Anodic Catalyst for Solid Oxide Fuel Cell Operated at Intermediate-temperature Direct Utilizing of Dimethylether Fuel

Abstract

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 BaCe_0.8Y_0.2O_3−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.
