中文摘要：

自增湿技术可以简化质子交换膜燃料电池（PEMFC）的系统，提高比功率，降低成本，促进PEMFC的商业化。从自增湿流场结构、自增湿复合膜、自增湿膜电极（MEA）等方面介绍了自增湿技术的研究现状和发展趋势。

英文摘要：

Self-humidifying technology could simplify the system of proton exchange membrane fuel cell （PEMFC）, improve the specific power, reduce the cost and accelerate the commercialization of PEMFC. The research status and development trend of self- humidifying technology Were reviewed mainly through three aspects： the flow-field structure of the self-humidifying system, self- humidifying composite membrane and the MEA of the self-humidifying system.
