abstract = {Based 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. Tietz, I. ArulRaj, Q. Ma,
