环境条件对质子交换膜燃料电池性能的影响

Effect of Environmental Condition on the Performance of Proton Exchange Mem-brane Fuel Cell

摘要: 研究了不同环境温度、湿度条件下小功率质子交换膜燃料电池(PEMFC)堆的性能。结果表明:环境温度、湿度对PEMFC堆的性能有很大影响,随着相对湿度的增加,PEMFC堆的最大输出功率显著提高;当相对湿度小于30%或者当环境温度降至10℃以下时,PEMPC堆的性能严重下降。

Abstract: The performance of a proton exchange membrane fuel cell (PEMFC) stack was investigated at different ambient temperatures and humidities. The results show that the relative humidity and the temperature of the surrounding air significantly affect the performance of the PEMFC stack, and the maximum output power of the PEMFC stack increases sharply with the increase of relative humidity. While the relative humidity is less than 30%, or the ambient temperature is below 10℃, the performance of the PEMFC stack deteriorates.
