Resumen

Sr2MgMo0.9Ni0.1O6-d (SMMNi) double perovskite was synthesized by the combustion-solution method followed by annealing in air at 1100 ºC during 12 hours. Sr2MgMoO6-d (SMMO) compound was also tested for comparison. X-Ray Diffraction (XRD) patterns indicate that SMMO and SMMNi powders display triclinic symmetry. Termogravimetric studies show that Mo-substitution by Ni in SMMO decreases the oxygen content in air condition. Meanwhile, after calcination in diluted-H2 both compounds present oxygen non-stoichiometric change Dd » 0.06. EIS measurements on symmetrical SMMO/GDC/SMMO and SMMNi/GDC/SMMNi cells were performed in order to study the influence of time and environment conditions (H2-content) on the anode polarization resistance (Rpa).
