隨著化石能源的逐漸枯竭和環(huán)境污染的日趨嚴(yán)峻,開(kāi)發(fā)新能源和新能量轉(zhuǎn)換裝置成為目前新能源領(lǐng)域的研究熱點(diǎn)。直接甲醇燃料電池（Direct methanol fuel cell,DMFC）是一種將化學(xué)能直接轉(zhuǎn)化成電能的裝置,具有燃料來(lái)源廣泛、比能量和比功率高、系統(tǒng)簡(jiǎn)單和環(huán)境友好等優(yōu)點(diǎn)。質(zhì)子交換膜（Proton exchange membrane,PEM）是直接甲醇燃料電池的核心部件,起到隔絕甲醇燃料滲透和提供質(zhì)子傳遞通道的作用,PEM的性能優(yōu)劣直接影響燃料電池的性能和使用壽命。目前,最常用的PEM為Dupont公司的Nafion系列膜,Nafion膜具有優(yōu)良的質(zhì)子導(dǎo)電性、高機(jī)械強(qiáng)度和化學(xué)穩(wěn)定性,但Nafion的全氟骨架制備過(guò)程復(fù)雜,成本高,并會(huì)對(duì)環(huán)境造成污染,并且Nafion膜存在燃料滲透嚴(yán)重和高溫低濕下質(zhì)子導(dǎo)電性衰減等缺點(diǎn),嚴(yán)重降低了直接甲醇燃料電池的能量密度和能量輸出,所以開(kāi)發(fā)高阻醇性能的新型聚合物質(zhì)子交換膜替代Nafion是當(dāng)前的研究熱點(diǎn)�；腔勖衙淹⊿ulfonated poly（ether ether ketone）,SPEEK）是工程塑料聚醚醚酮的磺化產(chǎn)物,具有甲醇滲透率低、機(jī)械...
