中文摘要：

质子交换膜燃料电池（PEMFC）是一种高效、低污染的发电装置.与其它类型的燃料电池相比,具有比功率高、操作温度低、耐腐蚀性好和寿命长等优点.质子交换膜（PEM）的性能对燃料电池的性能起关键作用.目前商业化的PEM膜材料仍然是全氟磺酸材料（如Nafion）,虽然其具有较好的稳定性和较高的质子传导率,但成本高,在低湿度或高温时的质子传导性较差,存在较高的甲醇渗透性等,阻碍了燃料电池的广泛应用.

英文摘要：

Poly（arylene ether ketone） carring multi-sulfonated side chain was prepared via graft polymerization reaction.The obtained soluble sulfonated polymer SP-Ⅰ and SP-Ⅱ have high viscosity（ηinh1.72 dL/g）.The transparence and tough sulfonated polymer film was obtained by solution casting method and exhibited good thermochemical stability,high proton conductivity（〉0.90 S/cm） and good dimensional stability.
