제목 Preparation of poly(benzimidazole)/imidazole modified graphene oxide composite membrane for high temperature polymer electrolyte membrane fuel cell application.
초록 Modified graphene oxide was incorporated into poly[2,2’-(m-phenylene)-5,5’-bibenzimidazole] (m-PBI) to prepare composite membrane for high temperature polymer electrolyte membrane fuel cell (HT-PEMFC). Graphene oxide (GO) was reacted with o-phenylenediamine to acquire imidazole graphene oxide (ImGO). The PBI/ImGO composite membrane exhibited improved mechanical, thermal properties and proton conductivities compared to pristine PBI membrane. At 150℃ and dehydrate condition, PBI/ImGO-0.5 composite membrane showed increased proton conductivity of 77.52 mS cm-1.
