Etude de la distribution du champ electrique resultant d'une anisotropie dans le transport des reactifs et des charges

The concept of a primary diffusion field having been defined, a method is proposed for the determination of the current distribution at an electrode when this distribution results from a combination of the processes at the interface, of diffusion and of electrolytic conduction. This method, which depends upon the formal analogy between a diffusion field and an electric field, consists in determining repeatedly, for each point on the electrode surface, a series of resistances representing the bringing together of the reactants, the discharge of the ions and the interface processes. It permits investigation of the current distribution whatever the cell geometry or the form of kinetics involved.
