In a previous work we studied the Nb incorporation at the Co positions in the SrCo1?xNbxO3?? system, in which the stabilization of a tetragonal P4/mmm perovskite superstructure was described for the x = 0.05 composition. In the present study we extend this investigation to the x = 0.10?0.15 range, also observing the formation of the tetragonal P4/mmm structure instead of the unwanted hexagonal phase corresponding to the 2H polytype. We also investigated the effect of Nb5+ doping on the thermal, electrical, and electrochemical properties of SrCo1?xNbxO3?? (x = 0.1 and 0.15) perovskite oxides performing as cathodes in SOFC. In comparison with the undoped hexagonal SrCoO3?? phase, the resulting compounds present high thermal stability and an increase of the electrical conductivity. The single-cell tests for these compositions (x = 0.10 and 0.15) with La0.8Sr0.2Ga0.83Mg0.17O3?? (LSGM) as electrolyte and SrMo0.8Fe0.2CoO3?? as anode gave maximum power densities of 693 and 550 mW?cm?2 at 850 °C respectively, using pure H2 as fuel and air as oxidant.
