Transport properties of Inion, the new perfluorinated membrane containing short side chains, and of hybrid materials designed by the incorporation of nanoparticles of cesium hydrogen phosphotungstate into it were investigated. The Inion membranes possess a proton conductivity of 16.8 mS cm−1 upon a contact with water at 25 °C, while the modification with cesium hydrogen phosphotungstate (1.2 wt%) increases their conductivity up to 34.8 mS cm−1 accompanied by the simultaneously decreased diffusion permeability.
