摘要
针对电池中膜电极失水或被水淹没两种情况对电池的危害,论述了水管理是质子交换膜燃料电池取得良好性能的关键因素之一;介绍了增湿方法包括外增湿法、内增湿法和自增湿法,排水方法包括静态排水法和动态排水法;介绍了各种增湿方法和排水方法的原理,并对其优缺点进行了评述。
Water management is one of the key factors for PEM fuel cells to ach ieve good performance. Two problems will occur in membrane electrode assembly(ME A) in PEM fuel cells: dehydration and flooding. In this paper water management c an be classified into water removing and humidification. The humidifying method was classified into three categories: external humidification ,internal humidifi cation and self-humidificaton. The removal method was classified into static wa ter removal and dynamic water removal.All of these methods and their principles were introduced in this paper.
