中文摘要：

燃料电池作为一种绿色环保的清洁能源，具有启动速度快、工作温度低、比功率大及操作方便等优点，是最有希望替代石油等化石能源的未来能源之一．作为质子交换膜燃料电池（PEMFC）和直接甲醇燃料电池（DMFC）的核心部件，质子交换膜的研制备受关注．

英文摘要：

Fluorenyl-containing sulfonated poly （ether ether ketone ketone） was synthesized through a postsulfonation method as the matrix, and AMPH-POSS [ octaminophenyl polyhedral oligomeric silsesquioxane ] was selected as filler to form acid-base enhanced proton exchange membranes by solution casting. The microstructure and some basic properties were investigated. The filler was well dispersed in the polymer matrix. The hybrid membranes exhibited improved swelling stability, selectivity and methanol permerbilities.
