An efficient method for the computation of current density and surface concentration distributions in electrochemical processes is analyzed using the commercial mathematical software FEMLAB. To illustrate the utility of the software, the procedure is applied to some realistic problems encountered in electrochemical engineering, such as current distribution in a continuous moving electrode, parallel plate electrode, hull cell, curvilinear hull cell, thin layer galvanic cell, through-hole plating, and a recessed disc electrode. The model equations of the above cases are considered and their implementations into the software, FEM-LAB, are analyzed. The technique is attractive because it involves a systematic way of coupling equations to perform case studies.
