| 摘 要： | 质子交换膜燃料电池(PEMFC)，具有高功率密度、高能量转换效率、低工作温度和环境友好的优点，被认为是第五代燃料电池和未来较为理想的电动汽车动力源之一。为了降低PEMFC中氧还原反应的电化学极化，提高电池的输出功率，目前普遍采用Pt作为催化剂。Pt资源匮乏，价格昂贵，研究开发更好的制备工艺以减小Pt金属尺

| Abstract: | Pt catalysts for PEMFC were prepared by microwave-sol process,which was a new efficient way to prepared nano materials.Tests of BET,XRD,TEM and PEMFC electrochemistry work station were adopted to analyze the relationship between synthesis way,crystal structure and Pt catalytic capability.The results showed that the samples prepared by microwave-sol process had more BET surface areas and pore size distributions,while the sizes of Pt particle were decreased,and the useful crystal for O_2 reduction were increased,too.The crystal transformation improved the electrocatalytic activity of Pt,and as a result,improved the performance of PEMFC. |
