摘　　要：构建了5kW氢空质子交换膜燃料电池(PEMFC)系统,电堆工作温度范围为室温到80℃,工作压力为200kPa;研究了5kWPEMFC的性能特点。结果表明:PEMFC性能随着气体压力和电堆温度的升高而提高。当氢气流量为46L/min、空气流量为120L/min时,电池性能最好。5 kW H_2-air proton exchange membrane fuel cell (PEMFC) system was assembled.The stack was operated at the (temperature) range from room temperature to 80 ℃ with the pressure of 200 kPa. The performance characteristics of the 5 kW PEMFC were studied .The results showed that the performance of PEMFC was improved by increasing the pressure of gas and the stack temperature,it obtained the best performance when the flow of H_2 and air were 46 L/min and 120 L/min respectively.
