Rare earth-doped ceria possesses mixed ionic and electronic conductivity and is considered to be a promising anode material for SOFCs operating on methane. They exhibit excellent activity for hydrogen oxidation and high resistively to carbon deposition when exposed to hydrocarbons. It has been reported that gadolinia-doped ceria anodes are able to tolerate redox cycling without degradation in their performance. At the same time, an electronic conductivity of gadolinia- and samaria-doped cerates of 0.1 S/cm is rather low and limits their use to the electrolyte-based SOFCs only. Doping with the pentavalent V2O5 showed a slight increase in Oe compared to pure CeO2. This suggested to be attributed to the introduction of cation vacancies, which react with oxide vacancies and shift Eq. 1 to the right. Consequently, this increases electronic and decrease ionic conductivity.
