modelCaFP
Cathode flow plate
Extends from Region (Base model for a 3D array of subregions).
Information
This model represents the cathode flow plate of a PEMFC. It is identical to the anode flow plate except for the included species, the default length of the channel, and the fraction of the volume for the fluid (ε). For more information, please see the anFP model.
