燃料電池以其高轉(zhuǎn)化率和無污染等特點,成為內(nèi)燃機動力領域最具競爭力的取代能源。質(zhì)子交換膜是其核心部件之一,在阻隔燃料同時為質(zhì)子的遷移和輸送提供通道。在高溫和/或低濕度環(huán)境下,質(zhì)子交換膜因劇烈失水而使其質(zhì)子傳導性能急劇下降,這極大地限制了燃料電池的大規(guī)模應用。
武培怡教授和湯蓓蓓副教授制備具有多種結構的無機納米粒子并將其用于質(zhì)子交換膜的改性研究,開發(fā)了系列具有高質(zhì)子傳導率、低甲醇滲透率的雜化質(zhì)子交換膜。改性后的質(zhì)子交換膜的質(zhì)子傳導率較改性前可提高2-10倍、選擇性最高可有1-2個數(shù)量級提升。相關系列研究成果發(fā)表在材料領域權威期刊J. Mater. Chem. A發(fā)表。詳見:
