The earlier fractional step algorithm for solving the diffusion-migration equation in electrochemistry is extended to a multi-dimensional multi-species system with second-order spatial accuracy. For each time-step increment, the algorithm consists of three stages: (i) diffusion, (ii) satisfaction of the electroneutrality constraint, and (iii) migration. Each stage accounts for one individual physical process. Exact analytical solutions are derived for a two-species system and comparisons between exact and numerical results are made. Numerical results are also obtained for a two-dimensional three-species electrochemical model. © 1995 John Wiley & Sons, Inc.
