A proper water management is important for an efficient operation of a polymer electrolyte membrane (PEM) fuel cell system. The humidity distribution in the anode gas channels is highly dependent on the cathode humidity and the resulting transmembrane water transport. Therefore, it can be assumed that the cell humidification is optimal when the relative anode humidity is nearly 100% and homogeneously distributed.

基于阳极气体通道中湿度分布的PEM燃料电池系统的水管理

适当的水管理对于聚合物电解质膜（PEM）燃料电池系统的有效运行很重要。阳极气体通道中的湿度分布高度依赖于阴极湿度和所产生的跨膜水传输。因此，可以假设当相对阳极湿度接近100％且均匀分布时，电池的加湿效果最佳。
