AB - Perovskite oxide La0.6Ca0.4Fe0.8Ni0.2O3−δ (LCFN) has been used in symmetric solid oxide cells (SSOCs) to obtain good electrochemical performance in both fuel cells (SOFCs) and electrolysis cells (SOECs) modes. However, its structural stability still faces challenges and the electrocatalytic activity also needs to be further improved. Herein, tungsten-doped La0.6Ca0.4Fe0.7Ni0.2W0.1O3−δ (LCFNW) perovskite oxide material was synthesized which exhibits good structural stability under H2 and superior electrochemical performance as an electrode for SSOCs. In SOFCs mode, the cell achieved the maximum power density of 0.58 W·cm−2 with wet H2 as fuel at 850 °C. In SOECs mode, the current density can reach 1.81 A·cm−2 for pure CO2 electrolysis at 2 V. Moreover, the SSOCs exhibits outstanding long-term stability in both SOFCs and SOECs modes, proving that doping W in perovskite oxide is an effective strategy to enhance the catalytic activity and stability of the electrode. The LCFNW material developed in this work shows promising prospect as an electrode candidate for SSOCs.
