Concentration overpotential has been measured in systems having mass transfer by forced convection caused by flow through a compartment bounded by ion-exchange membranes. The dependence upon current density of the difference between the bulk solution concentration and the apparent interfacial concen

This research work presents a simple, original and illustrative experimental method to investigate the concenlration polarization using a cation exchange membrane (CEM). The nature of the overlimiting current (Iov) and the water dissociation (WD) on the CEM are particularly studied. They are still w
