Mathematical modeling of electrochemical cell involving novel kinetics description

Abstract

We propose an alternative kinetic description of electrochemical interactions. The model is based on the balances of mass and electric charge and the kinetic equations for the electrode reaction. The rate of electrochemical reaction is dependent on the surface concentration of electric charge. The current-voltage characteristics of a selected electrochemical system are presented. In regimes not hindered by mass transport, the characteristics are in good qualitative agreement with those given by classical Butler-Volmer kinetics.
