AB Symmetrical solid oxide cells (SSOCs) with identical air and fuel electrodes have gained significant scientificinterest in the last decade because they offer several advantages over conventional cell configurations. Amongother features, simpler fabrication, better chemical and thermo-mechanical compatibility between cell layers,and electrode reversibility, make them attractive for electricity generation, H2 production and CO2 electroreduction.This review offers an overview of the most recent advances in the field of SSOCs, paying specialattention to the relationship between electrode composition, crystal structure and properties. With that aim,symmetrical electrodes are classified in four groups according to their redox stability, i.e. single phases, composites,electrodes with exsolved metal particles and those that suffer a drastic phase transformation underreducing conditions, known in the literature as quasi-symmetrical electrodes. Furthermore, an outlook of othercell configurations with increased scientific interest are also discussed, i.e. symmetrical protonic fuel cells(H–SSOCs) and solid oxide electrolyzers for CO2 electroreduction. With this overview in mind, the authors wouldlike to highlight the challenge ahead of finding electrode materials that optimally work under both oxidizing andreducing conditions in terms of redox stability and electrochemical properties, and further conclude on the futuredevelopment of SSOCs.
