What Can the Electrochemistry Module Do?
The Electrochemistry Module extends the COMSOL Multiphysics environment with customized physics interfaces for modeling of electrochemical cells, with tools for building detailed models of the configuration of electrodes and electrolyte. The physics interfaces include descriptions of the electrochemical reactions and the transport properties that influence the behavior of various types of electrochemical cells. With this module, you have the perfect tools to investigate the influence of using different materials, geometric configurations, and operating conditions on the behavior of a cell.
The targeted applications for this module are the following:
•
Electroanalysis
•
Rotating disc electrodes
•
Voltammetry
•
Chronoamperometry
•
Electrochemical impedance spectroscopy
•
Electrochemical sensors
•
Electrolysis
•
Electrodialysis
•
Biosensors
•
Electrochemical nanotechnology
The physics interfaces include chemical species transport, charge balances, heat transfer, and fluid flow. You can use the module to model electrochemical and electroanalytical procedures in electrochemical cells at different operating conditions for different electrode configurations, structures, and dimensions; and different electrode and electrolyte materials and chemistry.
The module adds the electrochemistry interfaces, which contains the Electroanalysis interface and the Primary Current Distribution, Secondary Current Distribution, and Tertiary Current Distribution, Nernst-Planck interfaces. The current distribution interfaces are available for solid nonporous electrodes and for porous electrodes. General tertiary current distribution models can also be set up using the Chemical Species Transport interfaces.
The tailored physics interfaces mentioned above are also complemented with extended functionality in other physics interfaces for chemical species transport, heat transfer, and fluid flow.
The physics interfaces for chemical species transport of neutral species are extended by adding functionality that directly couples to electrochemical reactions defined in the physics interfaces for electrochemical cells.
Heat Transfer
includes heat sources that describe ohmic losses in the electrodes and electrolyte and heat sources due to electrochemical reactions in electrochemical cells.
The fluid flow capabilities are extended for laminar flow, where the chemical species transport and the energy balances influence the properties of the flow.
