Vanadium Redox Flow Battery
Application ID: 14153
This 2D example of a vanadium flow battery demonstrates how to couple a secondary current distribution model for an ion-exchange membrane to tertiary current distribution models for two different free electrolyte compartments of a flow battery.
The Ion-Exchange Membrane boundary node specifies a boundary condition where the flux of ions is continuous, but where the electrolyte potential is discontinuous and is described by a Donnan equilibrium.
This condition is typically used in electrochemical cells containing both free electrolytes and ion-exchange membranes, for instance, in dialysis problems.
This model example illustrates applications of this type that would nominally be built using the following products:Batteries & Fuel Cells Module
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® and
- either the Batteries & Fuel Cells Module, Corrosion Module, Electrochemistry Module, or Electrodeposition Module
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 Specification Chart 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.
