Abstract: The microsturcture and performance of the recasting perfluorosulfonated membrane were investigated by comparison with Nafion . The results indicated that although chemical components of the recasting membrane FYM1150 kept the same as Nafion , the dry FYM1150 differed from dry Nafion  membrane in structure, the former possessed some small pores which are not through-holes having a diameter of 50～300 nm while the latter had almost no pores; The mechanical properties of the FYM1150 were better than those of Nafion ; The discharge performance at high current density of MEA using FYM1150 membrane as an electrolyte was also better than one using Nafion  as electrolyted due to the porous structure in the FYM1150.

Key words: The recasting perfluorosulfonated membrane, Microstructure & properties, Proton exchange membrane fuel cell, Nafion 
