[2 mechanisms of membrane electroconductivity with tetrachloro-2-trifluoromethylbenzimidazole (TTFB)].

It has been found during galvanostatic measurements under the conditions of diffusion overtension that charge transfer through the membrane is carried out by the transfer of a proton from a neutral form to an anion (acidic region), or by transfer of a negative charge--dimer due to the formation of a hydrogen bond between them on the membrane border (alkaline region).
