摘　　要：研究了阳极催化剂及电解质膜对直接二甲醚燃料电池(DDFC)性能的影响,并与直接甲醇燃料电池(DMFC)进行了比较。在低电压区,以Pt/C为阳极催化剂的DDFC性能较好;在高电压区,Pt-Ru/C的催化行为更好。DDFC的开路电压随着Nafion膜的增厚而升高,使用Nafion115膜的DDFC最大功率密度为46 mW/cm2。在低电流密度区,DDFC的性能优于DMFC;在高电流密度区,DMFC的性能较好,DDFC的最大功率密度约为相同条件下DMFC的84%。The effects of anode catalyst and electrolyte membrane on the performance of direct dimethyl ether fuel cell （DDFC） were investigated and compared with the direct methanol fuel cell （DMFC）. The DDFC with Pt/C as anode catalyst had better performance in low voltage regions, Pt-Ru/C had better catalytic behavior in high voltage regions. The open circuit voltage of the DDFC increased with the increasing of the thickness of Nation membrane, the DDFC using Nation 115 membrane had the maximum power density of 46 mW/cm^2. The DDFC showed higher performance than DMFC in the low current density regions;in the high current density regions, the DMFC had better performance, the maximum power density of the DDFC was about 84% of the DMFC in the same condition.
