In solid oxide fuel cells, the measured cell resistance is usually higher than the calculated value based on the electrolyte thickness. Such a phenomenon is called a constriction resistance and can be represented by a cell:electrolyte resistivity ratio, = cell : electrolyte , where cell = R cell /Δ±
In the present paper, we investigated the electrical performance of anode-supported solid oxide fuel cells (SOFCs) composed of Gd 0.1 Ce 0.9 O 1.95 (GDC) electrolyte films of 1-75 m in thickness prepared by simple and cost-effective methods (dry co-pressing process and spray dry co-pressing process)
