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 protonconductive properties and are characterized by a higher heat-exchange capacity compared with commercial membranes as Nafion and MF-4 SK, enabling to consider them as perspective membrane materials for fuel cells.

The thermal-oxidative stability of membranes based on poly-1-vinyl-1,2,4-triazole and phenol-2,4-disulfonic acid has been studied. It has been shown that an increase in the acid content in the membrane leads to an increase in thermal stability due to the formation of acid-base complexes
