Lithiated NiO was adopted as electrodes for doped-ceria based IT-SOFCs. Li0.3Ni0.7Oy electrode is chemically compatible with Ce0.8Gd0.05Y0.15O1.9 (GYDC) electrolyte in air. Single cell with configuration Li0.3Ni0.7O|GYDC|Li0.3Ni0.7O was fabricated by one step dry-pressing and sintering at 1200 °C. Maximum power density of 503 mWcm−2 at 0.5 V was achieved at 600 °C with H2 as fuel and air as oxidant. Cell stability test was carried out at 575 °C under a constant voltage of 0.3 V and a current output of 380 mAcm−2 was continually generated after an initial performance decrease. A stable anode is required for symmetrical IT-SOFCs.
► A one-step co-firing for SOFC has been demonstrated. ► Maximum power density of 503 mWcm−2 was achieved at 600 °C with H2 as fuel. ► A stable current of 380 mA cm−2 was observed after initial decrease. ► A more stable anode is required for symmetrical IT-SOFCs.
