| 英文摘要 | double-layered anode catalyst layers with two reverse configurations, which consist of 45 wt.% pt3sn/c and ptru black catalyst layers, were fabricated to improve the performance of a direct ethanol fuel cell (defc). the in-house 45 wt.% pt3sn/c catalyst was characterized by xrd and tem. the cross-sectional double-layered anode catalyst layer was observed by sem. in defc performance test and anode linear sweep, voltammetry measurement, the anode with double-layered catalyst layer exhibited better catalytic activity for ethanol electro-oxidation than those with single-layered 45 wt.% pt3sn/c and ptru black catalyst layers. in terms of anode product distribution, the defc with double-layered anode catalyst layer showed a higher yield of acetic acid than that with single-layered ptru black catalyst layer and a higher yield of co2 than that with single-layered 45 wt.% pt3sn/c catalyst layer, respectively. these results suggest that the double-layered anode catalyst layer possessed the advantages of both pt3sn/c and ptru black catalysts for ethanol electro-oxidation, and thus showed a higher ethanol electro-oxidation efficiency and defc performance in the practical polarization potential region.
