摘要:	The current study examined the effect of La(0.6)Sr(0.4)Co(0.2)Fe(0.8)O(3) (LSCF) and La(0.7)Sr(0.3)MnO(3) (LSM) coatings on the electrical properties and oxidation resistance of Crofer22 APU at 800 degrees C hot air. LSCF and LSM were coated on Crofer22 APU by screen printing and sintered over temperatures ranging from 1000 to 1100 degrees C in N(2). The coated alloy was first checked for compositions, morphology and interface conditions and then treated in a simulated oxidizing environment at 800 degrees C for 200 h. After measuring the long-term electrical resistance, the area specific resistance (ASR) at 800 degrees C for the alloy coated with LSCF was less than its counterpart coated with LSM. This work used LSCF coating as a metallic interconnect to reduce working temperature for the solid oxide fuel cell. (C) 2009 Elsevier B. V. All rights reserved.
