Formulation for the Prediction of Ionic Concentration Profile in an Electrochemical System

ABSTRACT:An analytical expression to predict the transient concentration profile of a charge-transporting cation in the electrolyte in the vicinity of the cathode electrode of an electrochemical cell is presented in this relatively short paper. To illustrate the application of the developed formulation, the computed data are presented in the form of the Z versus Y plots for four effective diffusivity values of the cation and noting the involvement of the Z(y)-function in the prediction of the cation transient concentration profile.
