Abstract The aim of this study was to examine the oxidation behavior and electrical conductivities of ferritic stainless steels STS444 coated with element Y for planar SOFC (solid oxide fuel cells) interconnects at 750℃. The effects of the main elements (Fe,Cr,Mn and Si) and the rare earth element Y on the growth of oxide scale and the high temperature electrical conductivity of STS444 alloy were studied using glow discharge spectrometer （GDS） and secondary ion mass spectroscopy （SIMS） techniques. The results indicated that the reactive element effects of element Y improved noticeably the oxidation resistance and electrical conductivities, and it can be possibly used as the candidate material for the SOFC interconnects.

Key words: solid oxide fuel cell metallic interconnect area specific resistance elevated temperature oxidation
