Determination of the Differential Resistance of a Bilayer Ion-Exchange Membrane according to the Theoretical Current–Voltage Curve

An analytical expression is obtained for the differential resistance of a four-layer electromembrane system consisting of a bilayer ion-exchange membrane with an uncharged layer and a layer with a constant through the thickness exchange capacity and two diffusion layers with the same thicknesses. Th...

Summary:An analytical expression is obtained for the differential resistance of a four-layer electromembrane system consisting of a bilayer ion-exchange membrane with an uncharged layer and a layer with a constant through the thickness exchange capacity and two diffusion layers with the same thicknesses. The degree of influence of the diffusion layers on the electrical resistance of the system is determined. An algebraic expression for the electrical resistance of a surface-modified ion-exchange membrane depending on the physicochemical characteristics of the layers of the bilayer membrane is obtained for the first time.
