3.2 The SOFC With Unresolved Electrolyte Modeling Strategy

To model solid oxide fuel cells (SOFC) with unresolved electrolyte, you need to perform the following:

• Capture the fluid flow, heat transfer, and the mass transfer in the flow channels and in the porous anode and cathode electrodes.

• Model the transport of the current and the potential field in the porous electrodes and in the solid conducting regions.

• Model the electrochemical reactions that take place at the electrolyte/electrode/gaseous species interface.
