Electrodiffusion of ions in ion exchange membranes: Finite element simulations and experiments
Chemical Engineering Journal Advances, 2021 Electrodiffusion of ions in both cation (CEM) and anion exchange membranes (AEM) has been studied with theoretical calculations and experimental studies. Calculations are based on the Finite Element Method (FEM) using COMSOL Multiphysics® software. Nernst-Planck equations are solved in multi-ionic systems where no closed form solutions are available ...
