Much effort is being devoted to investigating new electrode materials because the electrode polarization resistance remains a serious limitation to the performance. Nanostructured electrodes offer the possibility of increasing the SOFC efficiency at low temperatures. Among the different electrode preparation techniques, spray pyrolysis deposition is a versatile, economic and industrially scalable method to grow electrodes directly on the electrolyte, reducing preparation steps and time. Recent progresses in this field are summarized here, especially highlighting the wide variety of different microstructural strategies used to improve the electrode performance, i.e. nanocomposite cathodes graded cathodes, infiltrated cathodes and cathodes with active/functional layers. Finally, the current existing challenges and the future working directions for further enhancing the properties of new nanostructured electrodes are discussed. https://hdl.handle.net/10630/28450 10.1016/j.jpowsour.2021.230277 Pilas de combustible Electroquímica Recent progress in nanostructured electrodes for solid oxide fuel cells deposited by spray pyrolysis.
