The proton conductivity of the membranes based on MSC-H and Purolite CT-275 sulfonic cation- exchange resins being stable in polar mediums was investigated. The specific proton conductivity of the created membranes were (1÷2.3)·10-4 S/cm at 75÷95 °. This value is specified with membrane exchange capacity and the structure of the transported proton hydration sphere. Last one is depended on total temperature, membrane relative humidity and current intensity through the membrane.

Key word membrane, proton conductivity.
