제목 Highly proton conductive perfluorinated sulfonic acid ionomer reinforced membranes with improved chemical resistance for fuel cell application and valued chemical production
초록 Complicated PFSA production processes cause their cost to be high.When exposed in PEMFC operation conditions, PFSA materials experience critical chemical decomposition to radicals and physical failures occurred as a result of repeated membrane swelling and deswelling. In this study, an approach termed as “spontaneous pore filling technique under ambient pressure,” which is directly applicable to roll-to-roll processing for mass production, is developed. The resulting pore-filling membranes (PFMs) composed of a PFSA and pore-controlled PTFE support films exhibit defect-free and physically arranged morphologies. These materials are electrochemically evaluated for both hydrogen fuel cell and chlor-alkali applications.
