OS5-3 Development of Dimethylether Steam Reforming Catalyst for Fell Cell

We have developed a highly-active DME steam reforming catalyst with high activities of DME hydrolysis and methanol steam reforming. The addition of a certain kind of alumina to a Cu-Zn catalyst improved the steam reforming performance of DME. Two types of fuel-cell reforming systems have been evaluated under development ; external-heating type and autothermal type. The combination of a precious metal catalyst and a Cu-Zn-alumina catalyst has been found to be effective in the durability improvement to autothermal type.
