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.
