| 中文摘要 | In this study, an anode-supported solid oxide fuel cell (SOFC) has been prepared using a porous yttria-stabilized zirconia (YSZ) anode matrix. The anode was prepared by impregnating the sintered porous YSZ matrix with a nitrate aqueous containing La(3+), Sr(2+), Cr(3+), Fe(3+), Ni(2+) and urea. The formed anode exhibited high surface area and porosity, and had fast path for the transportation of oxygen ion and electron, as well as resulting in high three-phase boundaries (TPBs). Single-chamber fuel cell test was conducted in a methane-oxygen gas mixture using an YSZ membrane as the electrolyte and La(0.8)Sr(0.2)MnO(3-delta) (LSM) as the cathode. The influences of environmental temperature and gas composition on the cell performance were also investigated. Under the optimized gas composition (CH(4)/O(2) = 2/1) and furnace temperature (800 degrees C) conditions, a maximum power density of 214 mW cm(-2) was achieved. The test results demonstrated good cell stability and indicated that the perovskite oxide-based anodes were quite robust with redox cycling. (C) 2010 Professor T. Nejat Veziroglu.
