摘要
质子交换膜燃料电池是一种高效、清洁的新能源技术,被认为是未来能源最重要的发展方向之一,但燃料电池寿命短是目前阻碍电池商业化的重要因素之一。综述了近年来质子交换膜燃料电池耐久性研究进展,重点对膜电极的关键组成部分包括催化剂层、气体扩散层、质子交换膜的耐久性影响因素及常用膜电极寿命测试方法:工况循环法、启停循环法、循环伏安法、干湿循环法等进行了深入阐述。
Proton exchange membrane fuel cell(PEMFC) is an efficient and clean new energy technology and is considered to be one of the most important development directions for future energy.However,the short life of fuel cells is one of the important factors hindering the commercialization of fuel cells.In this paper,the recent research progress on the durability of PEMFC were summarized,especially focused on the factors related to the durability of the key components including catalyst layer,gas diffusion layer,and proton exchange membrane.The life test methods such as driving cycle,start/stop switches,cyclic voltammetry,humidity cycle were also deeply elaborated in this paper.
