New Proton-Conductive Membranes for Electromembrane Processes

Abstract

New hybrid organic-inorganic composites based on sulfur-containing styrene copolymers and allyl glycidyl ether and tetraethoxysilane were obtained by a sol-gel synthesis method. The membranes created on the basis of composites have high proton-conductive properties and are characterized by a higher ion-exchange capacity compared with commercial membranes as Nafion and MF-4 SK. These results alloy to consider composite membranes as perspective materials for fuel cells and another electromembrane processes.
