Summary

To minimize electrical resistance and maximize power output, contact layers are often applied between interconnects and electrodes during construction of a SOFC stack. This paper discusses the materials requirements for the electrical contact layers, particularly between cathodes and metallic interconnects. The results from the resistance measurements using simulated cathode/interconnect structures are reported and correlated to interfacial interactions occurring between the metallic interconnect and the contact materials, particularly perovskites.
