摘要：

The theoretical expression of the equilibrium polarisation resistance as a function of the partial hydrogen pressure and the activity of protons has been established for the hydrogen electrode reaction operating through the Volmer-Heyrovsky-Tafel mechanism. The corresponding elementary kinetic parameters have been evaluated using experimental results reported in the literature, obtained on smooth platinum electrodes. The advantage of the proposed method for the calculation of these parameters with respect to the conventional determination of the polarisation curves at high overpotential values has been also demonstrated.
