Estimate of Mass-Transfer Rate via Nernst Model with Ohmic Losses
Original language description
The liming-current technique, employed e.g. in electrodiffusion flow diagnostics, is based on an oversimplified electrochemical concept, which accounts only for the convective transport of depolarizers across a diffusion layer with constant bulk and wallconcentrations. However, there are additional transport resistances that cannot be neglected: Faradaic resistance at surface of working electrode, and Ohmic losses in the bulk of electrolyte solution. Effect of these additional resistances is analyzed using the Nernst model of a two-electrode cell (no reference electrode). The Faradaic resistances due to electrode kinetics are considered for a single redox couple O + ne- = R according to the Butler-Volmer electrode kinetics. The effect of Ohmic lossesis accounted for, considering primary current distribution for a uniformly accessible circular electrode.
