The electric field in the SCR of the depleted solution at the CEM (a) and AEM (b) as a function of the distance at different current densities, the values of which in mA·cm−2 are shown near the curves; x = 0 relates to the bulk solution, x = 1, to the membrane surface. The solid lines are calculated numerically, the dashed lines, using the analytical solution, Equation (A31).
