The hydrogen evolution reaction (HER) on platinum electrode in pure molten ethylammonium tetrafluoroborate (EABF4) has been investigated using a.c. impedance and potentiostatic steady-state polarization technique. The recorded impedance spectra have been discussed by an equivalent circuit approach and the theory of impedance of a quasi reversible electrode process preceded by a chemical (dissociation)reaction. The exchange current density of the HER, its activation energy, the diffusion coefficient of the hydrogen cation and the forward and backward rate constants of the preceding dissociation of ethylammonium cation have been determined.
