Model of a Proton Exchange Membrane Fuel Cell

This example demonstrates modeling of PEM fuel cell with interdigitated flow field design. This implies that a pressure gradient is imposed between the inlet and outlet channel systems and forces convective flow through the porous electrodes via Darcy's Law.

Mass transport assumes Maxwell-Stefan diffusivities, while equation-based modeling at the membrane-electrode interfaces includes a well-defined electrochemical kinetic expression.

Mass fractions of the reactant, normalized by their inlet values, on the anode side (left) and cathode side (right). Hydrogen is the reactant in the anode, and oxygen in the cathode.
