The solid oxide fuel cell (SOFC) electrochemically converts chemical energy into electrical energy. Interconnects are used to provide electrical connection to various individual cells in a stack for drawing useful electrical energy in the kW-MW range. By lowering the operation temperature to 800oC, the chromia-forming ferritic alloy interconnects become applicable. Their corrosion resistant chromia layer at the surface can form gaseous chromium oxides that lower the SOFC output by the cathode poisoning phenomena. Application of protective coatings can mitigate oxidation and form a resistant layer over the chromia. In this study, the electroless and electrolytic deposition methods were used to …
