Fuel Cell Cathode with Liquid Water
Application ID: 90161
This example extends the Fuel Cell Cathode tutorial to also include liquid water transport in the oxygen electrode.
Liquid water is produced using a user-defined expression for vapor condensation, depending on the relative humidity level in the gas phase.
An experimental capillary pressure curve is used to define the correlation between the liquid saturation level and the difference between the liquid and gas phase pressures.
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 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.
