Abstract
The regularities of the polarization of anthractie electrodes for the liberation of hydrogen from electrolyte (potassium chloride and hydrogen chloride) solutions were found, and electrode processes occurring at the surface of coals in the Fe2+/Fe3+ redox system were studied. It was found that the deviations of standard electrode potentials from the equilibrium values of redox systems depend on the exchange current densities of electrochemical processes occurring at the surface of coal matter. Low transfer coefficients (0.04–0.051) for the discharge reaction of hydrogen ions on anthracites indicate that the reaction occurs under conditions close to those of an activationless process.
