Abstract

The necessity for reducing the operating temperatures of solid oxide fuel cells (SOFCs) below 800 °C is widely proposed in the last years. To this aim, proton-conducting oxides have gained widespread interest as the electrolyte materials, acting as an alternative to oxygen ion conductors. High-temperature proton conductors, owing to their lower activation energy for proton conduction, can achieve high conductivity at relatively low temperatures compared to their oxygen ion-conducting counterparts. In this chapter, the recent advances in the field of solid oxide proton-conducting materials that belong to the class of perovskite-based materials (such as doped BaCeO₃, BaZrO₃, BaCeO₃–BaZrO₃ SrCeO₃, and LaScO₃) and to other classes of materials (such as doped Ba₂In₂O₅, CeO₂, and LaNbO₄) are presented and analyzed.
