| 摘 要： | 建立了质子交换膜燃料电池(PEMFC)和膜增湿器一维性能分析模型,模拟了空气流量、压力和温度等条件对PEM FC及膜增湿器性能的影响,模拟结果与实验数据吻合良好.根据模型对PEMFC膜增湿系统的非稳态性能进行了预测.空气进气温度的动态响应特性对膜内水含量梯度的影响显著,对膜内水的扩散系数几乎无影响.

| Abstract: | One dimensional performance analyzing model of both proton exchange membrane fuel cell(PEMFC) and membrane humidifier was developed.The effects of main conditions such as air flow rate,pressure and temperature on the performance of PEMFC and membrane humidifier were analyzed.The modeling results agreed with the experimental data.Unsteady performance of PEMFC membrane humidification system was predicted by the model.Inlet air temperature dynamic response characteristics effected water content gradient notably while had little effect on water diffusion coefficient in the membrane. |
