| Abstract Scope |
The protective coating of interconnect materials is essential in Solid oxide fuel cells (SOFCs) because of that high-temperature operation, interconnect material making chromium evaporation, and it makes cathode poisoning. To mitigate this issue, an alumina coating and a (Mn, Co)3O4-CeO spinel coating were developed at PNNL. The alumina coating provides an electrically nonconductive stable coating, and the spinel coating provides an electrically conductive and stable coating on the stack interconnects. However, the Mn-Co-O spinel contains Co, which is a relatively expensive material. Hence, if a cheaper element can be substituted, it could substantially reduce manufacturing costs. This paper summarizes recent efforts to replace Co with Ni or Cu. |
