Abstract
Lithiated NiO was adopted as electrodes for doped-ceria based IT-SOFCs. Li(0.3)Ni(0.7)O(y) electrode is chemically compatible with Ce(0.8)Gd(0.05)Y(0.15)O(1.9) (GYDC) electrolyte in air. Single cell with configuration Li(0.3)Ni(0.7)O vertical bar GYDC vertical bar Li(0.3)Ni(0.7)O was fabricated by one step dry-pressing and sintering at 1200 degrees C. Maximum power density of 503 mWcm(-2) at 0.5 V was achieved at 600 degrees C with H(2) as fuel and air as oxidant. Cell stability test was carried out at 575 degrees 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.
