温度对自增湿阴极开放式质子交换膜燃料电池（PEMFC）的性能有着重要的影响. 依据自制的常压自增湿型PEMFC及温度控制设备搭建测试平台，测试了燃料电池在不同工作温度下的输出特性曲线—伏安曲线和功率输出曲线. 通过拟合得到了电极过程动力学参数，分析了工作温度影响电池性能的主要原因.
Based on the experiments about the output characteristics of a home-made temperature-controlled PEMFC system with atmospheric pressure and no external humidifying condition in different loading voltages and operating temperatures, the optimum operating temperature at different loading voltages can be obtained by tracking the output characteristics of PEMFC operating over a range of temperatures. By analyzing the fitted data the kinetic parameters are evaluated and the effect of different operating temperatures on the PEMFC performance is discussed from a view of electrode kinetics.
