The catalyst is mainly used, because the overvoltage in the anode side is high for DDFC. And, CO arises under reaction, and the performance deterioration is generated by the CO toxification. Then, that it increases the quantity of the catalyst in the anode side and that it uses the Pt-Ru catalyst are effective. However, the performance is low, if DDFC using the Pt-Ru catalyst does not supply the water which is excessive for the cell in 100 degree or less. Then, the performance was compared by the supply of DME gas and DME aqueous solution. As the result, the cell which supplied the DME aqueous solution was lower than the performance which supplied Ihe DME gas. The performance of the cell which supplied the DME gas was improved by raising the humidifying temperature. Then, the performance of doing by the increase in the catalyst quantity, was improved, when the humidifying temperature was raised in the DME gas supply.
