In this work, we assess the effect of the addition of an aliovalent dopant (Sc3+) to the CeZr lattice in the generation of oxygen vacancies and its impact in the polarization resistance of CeZr and CeZrSc anodes when using diluted H2 and CH4 as fuels. The different electrode processes and rate-determining steps are analyzed as a function of temperature and variation of the fuel atmosphere.
