Description Ohmic resistance at the interface of the electrode and the interconnect in Fuel Cells influences the overall performance of a cell. In the present work, contact resistances between interconnect and electrodes in planar type Solid Oxide Fuel Cells (SOFC) under various compression loads and at different temperatures are measured in laboratory scale experiments. The roughness of the electrode and interconnect surfaces is characterized and a mathematical model to determine the contact resistance at the interfaces with known morphology, is proposed. The experimental results are found to be in good agreement with the values obtained from the model. (C) 2013 Elsevier B.V. All rights reserved.
