AC‐impedance method has been used successfully in characterizing a packed‐bed flow‐through electrode system. A macrohomogeneous model was developed to simulate the effect of structural, physical and flow parameters. The relative importance of kinetics and mass transfer can be inferred from the AC‐impedance analysis. Kinetic information about copper deposition in supported cupric sulfate solution has been obtained successfully using this technique.
