Abstract
The thin membrane of BaCe0.8Sm0.2O3-δ (BCS) with high quality was successfully fabricated on porous NiO-BCS anode substrate through a novel in situ reaction method. The key part of this method is to directly spray well-mixed suspension of BaCO3, CeO2 and Sm2O3 instead of pre-synthesized BCS ceramic powder on the anode substrate. After sintering at 1400 °C for 5 h, the extremely dense electrolyte membrane in the thickness of 10 μm is obtained. A single cell was assembled with La0.7Sr0.3FeO3-σ as cathode and tested with humidified hydrogen as fuel at 650 °C. The open circuit voltage (OCV) and maximum power density respectively reach 1.04 V and 535 mW/cm2. Interface resistance of cell under open circuit condition was also investigated.
