SOFC modeling considering hydrogen and carbon monoxide as electrochemical reactants

► A 2D SOFC CFD-FEM model in the cell scale is developed. ► Both carbon monoxide and hydrogen are included as electrochemical reactants. ► A fuel mixture without methane increases the need of air for cooling notably, i.e., giving low oxygen utilizations. ► The WGSR within the anode results in high mole fraction gradients in the direction normal to the main flow direction.
