The article is devoted to the study of the effect of various nanostructured carbon dopants (functionalized nanotubes, deagglomerated detonation nanodiamonds, nanocarbon) on the conductivity of Aquivion perfl uoropolymer membrane. The data on the composite materials production and the study of proton conductivity by impedance spectroscopy are presented in this paper. It found that the introduction of nanocarbon dopants in defi ned concentrations increases the conductivity of the Aquivion membrane.
