Resumen:
Starting from the modelling of the processes involved in the hydrogen oxidation reaction, the present work provides an explanation about the origin of the differences observed between the polarization curves obtained by voltammetric sweeps and those corresponding to the steady state measurements. It was demonstrated that the dependence on overpotential of the surface concentration of molecular hydrogen plays a key role in the current density profile. These concepts are illustrated and discussed on the basis of the voltammetric response of the reaction on platinum.
