AB La0.8Sr0.2MnO3-δ-Ce0.9Gd0.1O1.95 (LSM-CGO) nanostructured cathodes are successfully prepared in a singleprocess by a chemical spray-pyrolysis deposition method. The cathode is composed of nanometric particles ofapproximately 15 nm of diameter, providing high triple-phase boundary sites for the oxygen reduction reactions.A low polarization resistance of 0.046 Ω cm2 is obtained at 700 °C, which is comparable to the most efficientcobaltite-based perovskite cathodes. A NiO-YSZ anode supported fuel cell with the nanostructured cathodegenerates a power output of 1.4 W cm−2 at 800 °C, significantly higher than 0.75 W cm−2 for a cell with conventionalLSM-CGO cathode. The results suggest that this is a promising strategy to achieve high efficiencyelectrodes for Solid Oxide Fuel Cells in a single preparation step, simplifying notably the fabrication processcompared to traditional methods.
