摘　　要：采用Pt/C作阳极催化剂,Nafion115作电解质膜,组装成5cm2的单体电池。研究了电池温度,二甲醚浓度和流量对直接二甲醚燃料电池(DDFC)性能的影响。实验结果表明,温度从30℃上升到80℃,电池最大比功率提高了2.5倍;二甲醚浓度为1.5mol/L,流量为5mL/min时电池性能最佳,其最大比功率为56mW/cm2。The MEA with Pt/C anode catalyst and Nation115 membrane was investigated in this study. The effects of the concentrations and flow-rates of dimethyl ether （DME） solution, and the temperatures of the cell on performance for direct dimethyl ether fuel cell （DDFC） were investigated. The results show that the maximum power density of the DDFC at 80 ℃ was 56 mW/cm2, which is higher than that of DDFC at 30 ℃（16 mW/cm2）. DDFC with 1.5 mol/L and 5 mL/min DME solution shows the best performance, which the maximum power density is 56 mW/cm2.
