An intermediate temperature solid oxide fuel cell fabricated by one step co-press-sintering

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.
