Fuel Cell with Serpentine Flow Field

Application ID: 14449


This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen concentration. The overpotential is solved for along the cathode boundary by the use of a distributed DAE. The anode and membrane are modeled by the use of a lumped resistance.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
