Abstract:	La(0.6)Sr(0.4)Co(0.2)Fe(0.8)O(3) (LSCF) is applied on a Crofer22 APU interconnect for solid oxide fuel cells (SOFCs) by screen-printing method. The above coated alloy was first checked for their compositions, morphology and interface conditions. It was then tested in a simulated oxidizing environment, 800 degrees C for 200 h. The results showed that the LSCF film can change the oxidation behavior of Crofer22 APU. After sintering the screen printed alloy was under 1050 degrees C in N(2) atmosphere, the adhesion between the LSCF layer and alloy substrate is excellent. Long-term electrical resistance measurement indicated that area-specific resistance (ASR) of the alloy with coated film is significantly lower than that of the uncoated. The use of LSCF coating for metallic interconnect could reduce working temperature for solid oxide fuel cell. Published by Elsevier B.V.
