Chromia-forming ferritic stainless steels are preferred interconnect materials for intermediate temperature SOFCs because of their resistance to oxidation and low cost. However, they produce Cr-containing volatile species at SOFC operating temperatures, which can cause cathode poisoning. Hence, a protective coating is required on the surface of metal interconnect material. However, there are challenges in that the coating should not react with the cathode or sealing material, and also must show long-time stability. Moreover, the coated material should exhibit electrical conductivity for electrical contacting regions to the cathode surface and non-electrical conductivity for the rest of the surfaces, including sealing areas. Thus, spinel and alumina coating process have been developed by PNNL to enable durable sealing, prevent Cr evaporation, and maintain electrical insulation between stack repeat units, as well as electrical conductivity between stack unit and cathode material. Hence, a novel interconnect coating process is introduced in this paper.
