Technical information

　Solid Oxide Fuel Cell (SOFC) is a promised device for an effective utilization of natural gas. Nano-structured Pd/MnO2 shows the excellent catalysis as the anodic material in SOFC, compared to that of conventional Pt catalyst.

We found that a composite catalyst containing Pd/MnO2 and Fe particles, provides a significant improvement in the capability on a SOFC system using dimethyl ether as the raw fuel. This improvement will contribute effectively to realize a novel hybrid power system constructed with SOFC and diesel engine in near future.

Fig. 1 shows the performance of the SOFC using the composite catalyst as the anode at 600℃. The maximum performance was obtained as the output power density of 58.8 mWcm-2 when Fe-Pd/MnO2 (30 wt％):▲ was used in the anodic catalyst. This performance is larger than that of Fe, Pt, Ni, or Cu catalyst under the similar experimental condition used same SOFC system (Figs 2 and 3).
