Electrochemical Impedance Spectroscopy
Application ID: 14431
Electrochemical impedance spectroscopy (EIS) is a common technique in which a small oscillating perturbation is applied to an electrochemical system in order to investigate kinetic and transport properties. This example models EIS for a range of electrode reaction rates. Nyquist and Bode plots illustrate the transition between the reaction proceeding under kinetic or transport control.
This model forms the basis of an Electrochemistry Module Application Library app with the same title.
This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® et
- soit le Module Battery Design, Module Corrosion, Module Electrochemistry, Module Electrodeposition, ou Module Fuel Cell & Electrolyzer
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
