质子交换膜燃料电池的水热管理

Water and heat management problems in PEM fuel cell

对质子交换膜(PEM)燃料电池数学模型分别以一维、两维和三维的形式讨论,得出数学模型应向三维、非等温、两相流动的方向发展,逐步发展电堆模型;将现有的加湿方法分为外部加湿法、内部加湿法、自加湿法、直接加湿膜法和其他加湿法5类,论述了各种加湿方法的原理,并对其优缺点加以评述;介绍了质子交换膜燃料电池冷却系统的一般结构和原理。

Mathematical models of PEM fuel cell were introduced briefly.It was concluded th at three-dimensional,non-isothermal and two-phase flow model and the stack m o del should be included in the future work.The humidification methods were classi fied into five categories such as external humidification,self-humidification , direct humidification of the membrane and the principles of the humidification a nd cooling methods were introduced.
