The planar-type solid oxide fuel cell (SOFC) owes its design to the interconnector section which enables units of fuel cells to be stacked together. High operating temperature of SOFCs coupled with the gaseous environment, subjects this part to corrosion. To maintain its structural integrity, Fe-Cr...
