Abstract

Recently, La₂Mo₂O₉ has been presented as a promising electrolyte material for solid oxide fuel cells (SOFCs), and recent results from our group have confirmed that such compound fulfill some of the requirements for SOFCs applications such as a high ion conduction and a wide oxygen partial pressure range of pure ionic conduction. Nevertheless, the mechanism of oxygen conduction in La₂Mo₂O₉ is still not understood, in particular some questions remain about the strong decrease of conductivity from the cubic high-temperature (HT) phase to the monoclinic low-temperature (LT) phase. In the present work, some nanocompositional and nanostructural features of the LT-La₂Mo ₂O₉ superstructure that could explain the low conductivity of the LT-phase are put into evidence.
