Ceria and tin oxide were infiltrated in samariadoped ceria (SDC) anodes for use in intermediatetemperature solid oxide fuel cells (IT-SOFCs). It was found that ceria is able to stabilized tin as a molten metal in a reducing atmosphere up to 973 K, by preventing its coalescence and segregation. Moreover, electrochemical tests showed that the addition of tin significantly improves the performance of ceria towards the oxidation of hydrogen and methane. Impedance spectra suggested that the addition of tin affects conduction as well as reaction kinetics in the anode.
