Current Distribution and Potential Distribution

  • Fumio Hine


Much attention has been given to the design of electrolytic cells in the field of modern chemical engineering. One of the most important problems is the distribution of potential or current in such cells. The yield of products and the energy consumption are closely related factors. In some cases, quality of products depends on the potential distribution. In the case of electrochemical oxidation and/or reduction, for example, unwanted products may be generated as a result of uneven distribution of potential and current on the working electrode. In the case of electroplating and also of electrochemical winning of metals, the distribution of deposit, the current efficiency, and the soundness and structure of deposited metal are functions of the current distribution. Beginning with the pioneering efforts of Kasper, Wagner, and others, (1–7) the mathematical basis for predicting the distribution of potential and current has been firmly established. Because of mathematical difficulties associated with boundary conditions that describe polarization phenomena at the electrode surface, a completely general solution has not yet been obtained.
