摘 要:質(zhì)子傳導率超過(guò)Nafion膜的質(zhì)子交換膜是近年來(lái)研究的焦點(diǎn)。質(zhì)子交換膜的質(zhì)子傳導率與它們的IEC值和形態(tài)有關(guān)。形成離子通道是開(kāi)發(fā)高質(zhì)子傳導率的質(zhì)子交換膜的一種有效方法。形成離子通道主要有3種:1)用嵌段共聚物的微相分離;2)側鏈和支鏈磺化的聚合物;3)局部區域的高密集磺化。此外,與無(wú)機納米材料形成納米復合材料的質(zhì)子交換膜也能提高質(zhì)子交換膜的質(zhì)子傳導率及質(zhì)子交換膜的機械強度、尺寸穩定性、耐氧化穩定性等性能。綜述了關(guān)于用于高質(zhì)子傳導率的燃料電池質(zhì)子交換膜(PEM)的聚合物的研究進(jìn)展。對高質(zhì)子傳導率的燃料電池膜聚合物的發(fā)展趨勢進(jìn)行了展望。

Abstract:The proton exchange membranes(PEMs)presenting proton conductivities exceeding that of Nafion membrane were especially focused on in recent years. The proton conductivities of PEMs have been correlated to their ion exchange values and morphological phase separation. Formation of ionic channels is an effective approach to develop highly proton-conductive PEMs. There are three ways to the formation of ionic channels:1)development of microphase-separation with block copolymers,2)side-chain and grafted sulfonated polymers,and 3)locally and densely sulfonated polymers. Formation of nanocomposites of PEMs with nanofillers has also shown great ability to increase the proton conductivities of the existed PEMs. Besides proton conductivities,the formation of nanocomposites also improves some PEM properties including mechanical strength,dimensional stability and oxidative stability. The recent development of polymers for highly proton-conductive membrane was reviewed in this paper,and the future of these materials were also proposed.
Key words:proton exchange membrane;sulfonated polymers;fuel cells
