Modification of LSF-YSZ Composite Cathodes by Atomic Layer Deposition
Journal of the Electrochemical Society
Composite, Solid-Oxide-Fuel-Cell (SOFC) electrodes of La 0.8 Sr 0.2 FeO 3 (LSF) and yttria-stabilized zirconia (YSZ) were prepared by infiltration methods and then modified by Atomic Layer Deposition (ALD) of ZrO codeposited films of different thicknesses to determine the effect of surface composition on cathode performance. Film growth rates for ALD performed using vacuum procedures at 573 K for Fe 2 O 3 and 523 K for ZrO 2 and La 2 O 3 were determined to be 0.024 nm ZrO 2 /cycle, 0.019 nm Ladoi:10.1149/2.0181709jes fatcat:jl66vrdqxnbwvddctpcwvws37e
