Abstract
La0.8Sr0.2MnO3-δ (LSM) nanocatalyst-decorated Er0.4Bi1.6O3 (ESB) cathodes for IT-SOFCs were developed via an infiltration technique. Using different amounts of Triton-X 100 significantly changed the wettability of the LSM precursor solution, thus affecting final characteristics of the LSM nanoparticles. The best electrochemical performance was obtained at a 1:1 ratio of LSM and Triton-X 100. Furthermore, tuning the LSM concentration tailored the size and porosity of LSM nanocatalysts. The ASR of the optimized LSM-infiltrated ESB cathode on GDC electrolyte was as low as 0.16Ω-cm2 at 650°C, the lowest ASR among reported LSM-stabilized bismuth oxide cathodes fabricated by the infiltration method. © 2017 The Korean Society of Industrial and Engineering Chemistry.
