Carbon Corrosion in a Polymer Electrolyte Membrane Fuel Cell
Application ID: 140621
Carbon corrosion is one of the important degradation mechanisms in a Polymer Electrolyte Membrane (PEM) fuel cells which predominantly occurs during start-up or shut down of the fuel cells. During carbon corrosion, carbon support to catalysts is compromised affecting the cell performance.
In this model, the shut-down purging scenario is modeled by introducing air on the hydrogen (H2) side. If the gas flow channel on the H2 side is clogged by water, the scenario modeled here may arise.
This model 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:
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 Tabella delle Funzionalità 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.
