제목 Development of Highly Reinforced Pore-filling Electrolyte Membranes Based on Cross-Linked Benzoxazine-Benzimidazole Copolymers for Fuel Cells at High Temperature and Low Humidity Conditions
초록 Highly reinforced pore-filling electrolyte membranes, cosisted of sulfonated poly(arylene ether sulfone) (SPAES) derivatives as pore impregnated proton conducting electrolytes and cross-linked benzoxazine and benzimidazole copolymer as porous substrate, were developed for the application in polymer electrolyte membrane fuel cell operating at high temperature (> 100 oC) and low relative humidity (50% RH) conditions. The pore-filling membranes exhibited much improved dimensional and hydrolytic stabilities and mechanical strength than pristine SPAES membranes without much deterioration of proton conductivity. Subsequently,  cell performance of membrane electrode assemblies (MEAs) with the pore-filling membranes is much better than that with SPAES membrane at 120 oC and 40% RH conditions.
