Theoretical predictions of concentration difference (left) and macropore concentrations (right) comparing MCDI and SE + MCDI. The quantities used for the calculation are: Porosities $p_{\mu }=0.2\left(\mathrm{micro}\right),p_M=0.3\left(\mathrm{macro}\right)$; stern capacitance $C_{St}={10}^8{\mathrm{F}/\mathrm{m}}^3$; dimensions of, respectively, membrane, spacer and electrode: $L_{mem}=140\mathsf{\mu }\mathrm{m}$, $L_{sp}=500\mathsf{\mu }\mathrm{m}$, $L_e=300\mathsf{\mu }\mathrm{m}$; Charge densities of membrane and polyelectrolyte: $5\times {10}^3{\mathrm{mol}/\mathrm{m}}^3$, and 10³ mol/m³.
