000851084 520__ $$aBased on former research on perovskites in the quasi-ternary system LaFeO3–LaCoO3–LaNiO3[1], LaNi0.5Co0.5O3 (LNC) has been chosen as the most promising air electrode material for solid oxide cells (SOCs) in this system. In the present study, A-site deficiency of LNC is discussed and La0.97Ni0.5Co0.5O3 (LNC97) is selected as the further optimized composition, which has an electronic conductivity of over 1000 S cm-1 at 800oC. Compatibility of LNC97 with 8 mol% Y2O3 stabilized ZrO2 (8YSZ) is analyzed and compared with that of La0.58Sr0.4Co0.8Fe0.2O3-δ (LSCF) and 8YSZ. According to the requirements of the air electrode materials with qualified performance, i.e. 1) high electronic conductivity, 2) high ionic conductivity, and 3) high catalytic activity for the oxygen reduction reaction, LNC97 based electrodes are modified, characterized and optimized by symmetric cell tests. Degradation of the symmetric cells after 1000 h of operation is discussed. Mechanisms for explaining the electrode-processes of LNC97-based electrodes are raised, and full cells based on optimized LNC97 material show performance of about 900 mA cm-2 at 0.7 V and 800oC.[1] F.
