Abstract
The La0.6Sr0.4Co0.2Fe0.8O 3 (LSCF48) cathode material was used as a protective-conducting coating on an interconnect made of Crofer 22 APU ferritic steel intended for application in intermediate-temperature solid oxide fuel cell (IT-SOFC) stacks. The LSCF48 coating was deposited on the surface of the steel via screen-printing followed by appropriate thermal treatment. The oxidation kinetics of the Crofer 22 APU steel - uncoated and coated with LSCF48 - approximately obeys the parabolic rate law in air at 1,073 K under isothermal and cyclic oxidation conditions. The oxidation rate for uncoated steel is higher than that for coated steel. SEM-EDS and XRD investigations showed that the LSCF48 coating interacts with the steel during long-term oxidation in the afore-mentioned thermal conditions, and an intermediate multilayer interfacial zone is formed. This intermediate layer leads to lower area specific resistance in air at 1,073 K in comparison to the Crofer 22 APU steel without surface modification. © 2014 The Author(s).
