摘　　要：具有自增湿能力的低温质子交换膜燃料电池膜电极是实现自增湿燃料电池的重要途经,对于燃料电池的商业化具有十分重要的意义,它不仅可以大幅度减小燃料电池系统的体积,提升燃料电池系统的输出功率密度,还可以有效降低燃料电池的制造成本.目前,低温质子交换膜燃料电池自增湿膜电极的研究主要是集中在构建具有自增湿能力的质子交换膜、自增湿催化层和复合自增湿层三个方面.本文主要从这三个方面系统介绍近年来国内外低温质子交换膜燃料电池自增湿膜电极方面的研究进展和发展趋势.The self/non-humidification membrane electrode assembly(SH-MEA)is an important pathway towards the selfhumidification fuel cell and plays a crucial role for the large scale commercialization of low temperature proton exchange membrane fuel cell(LT-PEMFC),because it not only can reduce the volume and complexity of fuel cell system,resulting in the decrease of the cost,but also can improve the output power density of the fuel cell system.Currently,the researches on the self-humidifying MEA of LT-PEMFC mainly focus on three aspects:the preparation of self-humidification proton exchange membrane,the construction of self-humidification catalyst layer,and the construction of composite self-humidifying layers.In this paper,the research progress and development trend in self-humidifying MEA for low temperature proton exchange membrane fuel cell in recent years are reviewed.
