Sulfonated radiation grafted polystyrene pore-filled poly(vinylidene fluoride)membranes for direct methanol fuel cells:structure-property correlations

摘要

The growing demand for low methanol permeable,highly conductive and cost-effective proton-conducting membranes for direct methanol fuel cells(DMFCs)has derived many research efforts towards the development of new membrane materials.Pore-filled membranes bearing sulfonic acid groups are potential alternative membranes.We reported the preparation of pore-filled membrane composed of polystyrene sulfonic acid(PSSA)anchored in microporous poly(vinylidene fluoride)(PVDF)films.
