We present new nanostructured ceria-based anodes for IT-SOFCs operated under hydrogen or hydrocarbons. Ceria-based materials are mixed ionic/electronic conductors under reducing atmosphere, so fuel oxidation can be produced in their entire surface. These new nanostructured anodes exhibit high performance probably due to the dramatic increase of the number of active sites for fuel oxidation caused by the increase of the specific surface area.
