摘　　要：分析了质子交换膜燃料电池(PEMFC)中凝水的生长过程,分析了运行时间、电流密度、流速、温度、压力、湿度、流场和扩散层等因素对凝水的影响,并介绍了凝水的处理方法。对PEMFC凝水的可视化观测已从宏观步入微观。The process of water buildup in proton exchange membrane fuel cell （PEMFC） was analyzed. The influences of operating time, current density, flow speed, temperature, pressure, humidification, flow field and gas diffusion layer on water buildup were analyzed, the treating methods of water buildup were discussed. The visualizing observation of water buildup in PEMFC was developed from macro to micro.

关 键 词：质子交换膜燃料电池(PEMFC) 凝水 排水 水管理
