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:
