Investigation of ion concentration and electric potential distributions in charged membrane/electrolyte systems

For systems with unequal electrolyte bulk concentrations in contact with the membrane, current flow appears in the system due to the establishment of concentration and potential gradients in the system. The current flow increases with the increase in the bulk electrolyte concentration difference. The current flow in the multi-component electrolyte system is found to be smaller than that for the single-component system due to the increase in dimensionless Debye length.
