Composition-gradient protective coatings for solid oxide fuel cell interconnectors

•Protective Ni-based coatings on stainless-steel current collectors were developed.•Testing under solid oxide fuel cell (SOFC) cathodic conditions for 21,000 h.•Ni-based coatings effectively suppress Cr diffusion from the steel at 1123 K.•Microstructure and composition gradient in the reaction layer...
