In this paper A-site deficient (La0.25Sr0.25Ca0.45)yTi0.95Ni0.05-xCoxO3- d (LSCTNCA-) with different ratios of Ni and Co is presented. LSCTNC is a promising perovskite (ABO3) type mixed ionic-electronic conductive (MIEC) anode material for solid oxide fuel cells (SOFCs). LSCTNC has good electronic and ionic conductivity at low oxygen partial pressures, which allows efficient electron and ion transfer and is precondition of high MIEC anode activity. LSCTNC has good thermal stability and mechanical properties, which is important for the long-term durability of SOFCs. A significant amount of attention has been paid to clarify stability issues if the material is used as an anode in a solid oxide fuel cell. So far, there is a lack of information about the dependence between A-site stoichiometry and stability of chemical composition- and electrochemical performance of those type materials.
