Abstract
is deposited into a conventional Ni/yttria-stabilized zirconia (YSZ) anode to provide more active oxygen exchange kinetics and electronic conductivity compared to YSZ. The resulting nanoengineered cell with an effective size of 4 cm × 4 cm delivers a remarkable power output of 19.2 W per single cell at 0.6 V and 750 °C. These advancements have potential to facilitate the future development of high-performance SOFCs at a large scale by nanoengineering of electrodes and are expected to pave the way for the commercialization of this technology.
