제목 Characterization and comparative proton conductivity performance review by adding various heteropolyacid to the 2.5-PBI based PEMFC
초록 The method forming a stable proton conducting materials consisted in silicotungstic acid(TSA) and mesoporous silica were synthesized using sol-gel technique and functionalized after preparation,Among these H.P.A testing,  TSA group dispersed in 2.5-PBI group shown highest proton conducting value ,wherea TSAS(calcined) H.P.A group shown lowest values at the ion conducting performances. This because hydroxyl ion ,proton carrier,in H.P.A was decreased so this reacts free volume smaller however as increasing the content of heteropoly acid to the membrane, proton conductivity was generally increased.
