Current Distributions and Electrode Shape Changes in Electrochemical Systems

Chapter 1. The Current Distribution in Electrochemical Systems

Abstract

An electrochemical system consists in general of ionic solutions bounded by electrodes, membranes and insulators (fig. 1.1). At the electrodes electrochemical reactions take place. The flow of electrons in the outer circuit is converted into a flow of ions in the electrolyte.

Chapter 2. Solution of the Potential Model

Abstract

To find primary current distributions, a lot of classical analytical tools are available (superposition, con- formal mapping, method of images, …) [15]. Once the geometry is too complex or when non-linear overpotentials are considered, approximate methods must be used.

Chapter 3. The Boundary Element Method to Solve Current Distributions

Abstract

Much effort has been made to obtain a flexible general usable program. For that purpose a powerful data generator and postprocessor were developed.

Chapter 4. Electrode Shape Change

Abstract

In the previous chapter we discussed the possibility to calculate quickly current distributions. The simulation of electrode shape change can now be tackled.

Chapter 5. General Conclusion

Abstract

In this work we applied the boundary element method for the solution of many current distribution problems in electrochemical systems, including electrode shape change simulations.
