Abstract
A composite proton conducting membrane having covalently bonded acidic functional groups and at least 150 m 2 A composite proton conducting membrane comprising an inorganic filler with a high surface area of 1000000 / g and a water-insoluble ion conducting polymer, which offers advantages over conventional polymeric proton conducting membranes for redox flow battery, fuel cell and electrolysis applications, including: 1) enhanced proton conductivity / permeation due to the formation of additional nanochannels for proton conduction, 2) improved proton / electrolyte selectivity for redox flow battery applications, 3) reduced membrane swelling and gas or electrolyte crossover, 4) improved chemical stability, 5) increased cell operating time with stable performance, and 6) reduced membrane cost.
