(Mn,Co)3O4 spinel coatings on ferritic stainless steels for SOFC interconnect applications
TL;DR: In this article, a slurry-coating technique was developed for fabricating the spinel coatings onto the steel interconnects, which not only significantly decreased the contact resistance between a LSF cathode and stainless steel, but also acted as a mass barrier to inhibit scale growth on the stainless steel and to prevent Cr outward migration through the coating.

Selection and Evaluation of Heat-Resistant Alloys for SOFC Interconnect Applications
TL;DR: In this paper, the authors proposed that the interconnect metal or alloy should possess the following properties: (i) good surface stability (resistance to oxidation, hot corrosion, and carburization) in both cathodic (air) and anodic (fuel) atmospheres; (ii) thermal expansion matching to the ceramic PEN (positive cathode-electrolyte-negative anode) and seal materials (as least for a rigid seal design); (iii) high electrical conductivity through both the bulk material and in-situ formed oxide scales; (
