Abstract

Lithiated NiO was adopted as electrodes for doped-ceria based IT-SOFCs. Li 0.3Ni 0.7O y electrode is chemically compatible with Ce 0.8Gd 0.05Y 0.15O 1.9 (GYDC) electrolyte in air. Single cell with configuration Li 0.3Ni 0.7OGYDCLi 0.3Ni 0.7O 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 H 2 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. © 2011, Hydrogen Energy Publications, LLC.
