【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。更多还原

【Abstract】 The performance of a proton exchange membrane fuel cell (PEMFC) stack was investigated at different ambient temperatures and humidities. The results showed that the relative humidity and the temperature of the surrounding air significantly affected the performance of the PEMFC stack, and the max output power of the PEMFC stack increased sharply with the air humidity rising. While the relative humidity was less than 30%, or the ambient temperature dropped below 10℃, the performance of the PEMFC stack deteriorated.更多还原
