Ion Transport in Hybrid Membranes Based on Perfluorosulfonic Polymers
Abstract A comparative study of the transport characteristics of Nafion and Aquivion perfluorinated membranes and hybrid membranes on their basis has been carried out. It has been shown that the modification of membranes of both types with acid salts of heteropoly acids and silica significantly increases their proton conductivity. In the case of high humidity, the best conductivity is achieved when they are doped with salts of heteropoly acids. The highest improvement in the membrane conductivity is achieved at low humidity for membranes doped with SiO2; in this case, the conductivity is increased by almost an order of magnitude.
