摘要: The steady-state, transient and small-signal ac responses of ion exchange membrane systems are studied by using the network simulation method. A model for Nernst-Planck Poisson equations is used to describe ionic transport processes through a cation-exchange two diffusion boundary layers on both sides membrane. With this electric circuit programme PSpice, chronoamperometric, chronopotentiometric simulated. In work, we analyse influence fixed-charge concentration inside (1) steady-state current-voltage characteristic, (2) fluxes ratio describing permselectivity membrane, (3) chronoamperometric response, (4) response (5) electrochemical impedance. Some results obtained highly charged membranes can be compared with analytical solutions in ideal membranes.
