Abstract: A bilayered hydrocarbon/Nafion membrane with a ball and socket joint interface is presented to overcome the chemical stability issue of hydrocarbon membrane in VRFB application. Protective coating of chemically stable Nafion ionomers on hydrocarbon membranes can retard the degradation, and the ball and socket joint structure strongly binds the two chemically dissimilar membranes without generating additional interfacial resistance for proton conduction.
