摘　　要：分析了质子交换膜燃料电池堆进口的加湿水含量和出口气体的水含量,得出了电堆冷凝回收自加湿运行时冷凝器出口处温度的判别式。结果表明:自冷凝回收的温度仅与进气的过量系数有关。该方法简易可行,可用于实际车载工况和固定电站的高性能、长时间的自加湿运行。Based on the analyze of the water flow flux in the inlet and outlet in proton exchange membrane fuel cell（PEMFC） stack,the discriminant of the temperature in the condenser outlet for self-humidity operation is deduced.The results show that self-humidification temperature is merely a function of the stoichiometry,due to its simplicity,it can be used in large power applications or long time operation,especially in automotive applications.
