Proton Conducting Ionomer Membranes Based on Silicotungstic Acid/silica and Polybenzimidazole

In the last years, great interest has been devoted to the development of new polymer electrolyte membranes for fuel cells application as a valid alternative to the conventional perfluorosulfonated membranes. It has been recently shown that composite polymer membranes can be obtained by using a base sulfonated polymer filled with inorganic high proton conductive materials to improve base material properties.
