Behavior of a Model Bipolar Cell with Cylindrical Electrodes

Abstract

A type of bipolar cell, which consisted of graphite rods as bipolar electrodes, was constructed as a model of the packed bipolar cell. Behavior of this cell was investigated in the electro-deposition of copper from dilute solutions of copper ( II ) sulfate. The effective cathode area on each electrode was dependent on the applied voltage. The maximum energy efficiency was attained at a certain voltage. These results are discussed on the basis of the concept of threshold voltage and linear potential gradient in solution.
