Solid oxide cells (SOCs) devices are of great interest for efficient and clean power generation. An important component of the SOC stack is the metallic interconnect. It allows the fuel and oxygen gas separation and provides an electrical connection between the anode and the cathode of two neighboring cells. Chromia-forming ferritic stainless steels are widely used as interconnect materials in solid oxide cells. However, chromium evaporation and corrosion may negatively affect the component durability and efficiency. Ceramic coatings play a key role to limit these degradation issues. In particular, Mn-Co spinel coatings and Mn-Co doped spinel coatings are proposed as a viable solution, thanks to their high electrical conductivity and Cr retention capability.
