| 摘 要： | 引言质子交换膜燃料电池(PEMFC)除具有燃料电池的一般特点之外,还具有可在室温下快速启动、无电解质流失、寿命长、比功率与比能量高等突出优点,因而成为当今最具发展前景的一类燃料电池。由于工作温度低于100℃,主要采用过电势较低且活性较高的Pt为电催化剂,因此它存在价

| Abstract: | The Pt-Ru/C, Pt-Sn/C and Pt-Au/C catalysts were prepared by reduction of the precursors in appropriate solvents. The distribution and size of metal particles were characterized by TEM. The alloy conditions of the metals were characterized by XRD. The EIS tests and PEM single fuel cell test were conducted to show the performance to hydrogen oxidation and the CO tolerant ability of the catalysts. All of the results showed that Pt-Ru/C was the best one of the three catalysts, Pt-Sn/C next to it. |
