Abstract
Flat-plate SOFCs are supplied with interconnector plates with channels for the gas transport and ribs for the electrical contact. Utilization of the area underneath the rib is depending on in-plane diffusion of reactants through the electrode. The diffusion-limited current density underneath the rib was modelled, and the results are given in dimensionless form.Keywords
