Abstract
A novel composition of BaCe0.7Ta0.1Y0.2O3−δ (BCTY10) electrolyte membrane was successfully fabricated on porous NiO-BCTY10 anode substrate. The anode was prepared through a route combining a solid state reaction and a wet chemical method. After sintering at 1450 °C for 5 h, the BCTY10 membrane showed adequate chemical stability against CO2 and H2O. With a mixture of La0.7Sr0.3FeO3−δ (LSF) and BaCe0.7Zr0.1Y0.2O3−δ (BZCY7) as cathode, a single fuel cell with 25 μm thick BCTY10 electrolyte generated maximum power densities of 195, 137, 84, 44 mW/cm2 at 700, 650, 600 and 550 °C, respectively. The interface resistance of the cell under open circuit condition was also investigated.
