Abstract—: The influence of nanostructure carbon additives (functionalized nanotubes, deaglomerated detonation nanodiamonds, nanocarbon) on the conductivity of the Aquivion perfluoropolymer membrane is studied. In the work the data are presented on the manufacturing of the composite materials and the investigation of their proton conductivity via the impedance spectroscopy method. It is found that the introduction of nanocarbon dopants in a certain concentrations increases the conductivity of the Aquivion membrane.
