The properties of the membranes such as proton conductivity , water uptake , swelling degree and thermal stability were measured . results show that the sulfonated sbs membranes had good proton conductivity , at the same time , the water uptake and the swelling degree could meet the need of fuel cell 通過(guò)對(duì)不同磺化度的質(zhì)子交換膜的電性能、吸水率、溶脹率以及熱穩(wěn)定性等性能進(jìn)行了研究,表明磺化sbs膜具有了比較好的質(zhì)子傳導(dǎo)能力,吸水率與溶脹率也能滿足燃料電池的工作需求。
