A newly developed low-Cr containing Fe-Cr-Co alloy, named as FeCro, is evaluated as a candidate material of metallic interconnects for intermediate temperature solid oxide fuel cells (IT-SOFCs). This alloy possesses excellent oxidation resistance and adequate electrical conductivity at 750 degrees C in air, and shows slight Cr deposition in/around La0.72Sr0.18MnO3(LSM) electrode under a harsh accelerating condition of 400 mA cm(-2) and 850 degrees C. The thickness of the oxide scale thermally grown at 750 degrees C in air for 1000 his less than 1 mu m, presenting a double-layered structure with dense (Mn, Cr)(3)O-4 on the top of Cr2O3. The oxidation kinetics at 750 degrees C obeys the parabolic law with a low rate constant of 1.42 x 10(-15) g(2) cm(-4) s(-1). The Cr deposition in/around the LSM electrode in the presence of the FeCro alloy is remarkably reduced, compared to the commercial Crofer 22H alloy. The measured area specific resistance (ASR) at 750 degrees C in air after 1000 h isothermal oxidation is 14 m Omega cm(2). It is the unique microstructure of the formed oxide scale that significantly enhances the resistances of the FeCro alloy to oxidation and Cr volatilization. (C) 2014 Elsevier B.V. All rights reserved.
