摘要: The high reactivity between bismuth oxide and cobaltite oxygen electrodes is a bottleneck in developing active reliable oxide–cobaltite composite for solid cells (SOCs). Herein, Sr-free Sm0.95Co0.95Pd0.05O3−δ (SmCPd) electrode decorated with nanoscale Er0.4Bi1.6O3 (ESB) synthesized assembled on barrier-layer-free Y2O3–ZrO2 (YSZ) electrolyte film. cell the ESB SmCPd exhibits peak power density of 1.81 W cm−2 at 750 °C 0.58 650 °C. More importantly, excellent operating stability achieved fuel mode 600 500 h, electrolysis reversible modes over 200 h. results demonstrate feasibility applying high-performance durable SOCs.
