Batteries & Fuel Cells Module
The Module features tailored interfaces to study primary, secondary, and tertiary current density distributions in electrochemical cells. Electrode reactions, which are fully coupled to the transport phenomena, provide full descriptions of the electrode kinetics including activation and concentration overpotential. The cell can contain solid or porous electrodes with dilute or concentrated electrolytes. Furthermore, couplings of the electrochemical reactions and mass transfer in batteries and fuel cells to other phenomena, such as heat transfer, electric potential, and fluid flow, can be performed through the powerful capabilities of COMSOL Multiphysics.
