The Electrochemistry Module User’s Guide gets you started with modeling using COMSOL Multiphysics. The information in this guide is specific to this module. Instructions how to use COMSOL in general are included with the COMSOL Multiphysics Reference Manual.

To help you navigate through this guide, see the Glossary of Terms.

The Modeling with Electrochemistry chapter discusses a variety of topics, including Fundamentals of Electrochemistry Modeling, Modeling Electrochemical Reactions, Modeling Cyclic Voltammetry, and Postprocessing Your Solution.

Electrochemistry Interfaces chapter describes the Primary Current Distribution, Secondary Current Distribution, Tertiary Current Distribution, Nernst-Planck, Current Distribution on Edges, BEM, Electrode, Shell, and Electroanalysis interfaces. The chapter also includes the underlying theory.

Chemical Species Transport Interfaces chapter describes the Transport in Diluted Species, Transport of Diluted Species in Porous Media, and Surface Reactions interfaces. It also includes sections about the underlying theory for each physics interface.

Fluid Flow Interfaces chapter describes the Darcy’s Law, the Brinkman Equations, the Free and Porous Media Flow, Brinkman, and the Free and Porous Media Flow, Darcy interfaces, including the underlying theory for each.

Heat Transfer chapter describes how to couple electrochemical heat sources to heat transfer.

The Multiphysics Coupling Nodes chapter describes the coupling nodes available under the Multiphysics node for coupling various electrochemical interfaces using potential or space charge density couplings, for example.
