Title: ELECTRICAL CONTACTS BETWEEN CATHODES AND METALLIC INTERCONNECTS IN SOLID OXIDE FUEL CELLS

Abstract

To minimize electrical resistance and maximize power output, contact layers are often applied between interconnects and electrodes during construction of a SOFC stack. In this work, simulated cathode/interconnect structures were used to investigate the effects of different contact materials on the contact resistance between a LSF cathode and a Crofer22 APU interconnect. The results from the resistance measurements are reported and correlated to interfacial interactions occurring between the metallic interconnect and the contact materials, particularly perovskites. The materials requirements for the contact layers between cathodes and metallic interconnects in intermediate temperature SOFCs are also discussed.
