Abstract:<\/h4>\n
Solid oxide fuel cells (SOFCs) are power-generating devices with high efficiencies and considered as promising alternatives to mitigate energy and environmental issues associated with fossil fuel technologies. Nanoengineering of electrodes utilized for SOFCs has emerged as a versatile tool for significantly enhancing the electrochemical performance but needs to overcome issues for integration into practical cells suitable for widespread application. Here, we report an innovative concept for high-performance thin-film cathodes comprising nanoporous La0.6<\/sub>Sr0.4<\/sub>CoO3<\/sub>–<\/sub>\u03b4<\/sub> cathodes in conjunction with highly ordered, self-assembled nanocomposite La0.6<\/sub>Sr0.4<\/sub>Co0.2<\/sub>Fe0.8<\/sub>O3<\/sub>–<\/sub>\u03b4<\/sub> (lanthanum strontium cobalt ferrite) and Ce0.9<\/sub>Gd0.1<\/sub>O2<\/sub>–<\/sub>\u03b4<\/sub> (gadolinia-doped ceria) cathode layers prepared using pulsed laser deposition. Integration of the nanoengineered cathode layers into conventional anode-supported cells enabled the achievement of high current densities at 0.7 V reaching ~2.2 and ~4.7 A\/cm2<\/sup> at 650 \u00b0C and 700 \u00b0C, respectively. This result demonstrates that tuning material properties through an effective nanoengineering approach could significantly boost the electrochemical performance of cathodes for development of next-generation SOFCs with high power output.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1038\/s41467-021-24255-w Authors: Katherine Develos-Bagarinao, Tomohiro Ishiyama, Haruo Kishimoto, Hiroyuki Shimada, Katsuhiko Yamaji Abstract: Solid oxide fuel cells (SOFCs) are power-generating devices with high efficiencies and considered as promising alternatives to mitigate energy and environmental issues associated with fossil fuel technologies.
