In the present work, SrCo1-xMoxO3-δ (0 ≤ X ≤ 1) perovskites were synthesized by gel-combustion method with a non-stoichiometric route. Crystal structure and reducibility of the samples are correlated with their composition on B site of perovskite to identify those samples that exhibit phase stability at room temperature in both air and reducing atmosphere, which could become potential electrode materials for IT-SSOFCs. Furthermore, electrolyte densification is studied as a function of the pressure and heat treatments during pellet fabrication, as well as possible electrode-electrolytereactivity.
