The purpose of this paper is investigation of the PEFC performance by using methanol/H2 mixed gas and comparison with the PEFC performance by using DME/H_2 mixed gas. The results obtained are as follows. (1) The results showed that performance by using methanol/H_2 mixed gas lowers open circuit voltage, as compared with performance by using H_2 gas. And open circuit voltage lowers with the increase of methanol concentration in the anode gas. Cross leak of the methanol seems to be a cause, because the carbon dioxide was detected in cathode exhaust gas by using gas chromatograph. (2) The result tested by using DME/H_2 mixed gas, there was no change at the open circuit voltage. From the above fact, DME seems to excel the methanol as a reforming fuel
