Fabrication and Characterization of Anode-supported SDC Film Electrolyte and Its Single Cell
NiO-YSZ (NiO-yttria stabilized zirconia,3 :2,wt.％) and samaria doped ceria (SDC) tapes were prepared by aqueous tape casting. NiO-YSZ anodesupported SDC film electrolyte half-cell was fabricated by laminating and co-sintering at 1400℃ for 2 h. The single cell was prepared after LSCF-SDC (lanthanum strontium cobalt ferrite-SDC. 1:1,wt.％) cathode was coated on the electrolyte surface and sintered at 1300 ℃ for 2 h. The discharge performance of the single cell was tested from 500℃ to 800℃ at different H2 flow rate. Results showed that the relationship between current (l) of and H2 flow rate (v) was I = 8 x 106 v. Before reaching the threshold value of H2 flow rate,the current density of single cell increased with the increasing of H2 flow rate. However,the current density did not change with increasing of H2 flow rate over the threshold value. The open circuit voltage (OCV) of single cell at 500℃,600℃, 700℃,800℃ was 0.978,0.921. 0.861,0.803 V, respectively. The maximum power density reached 93.03 mW/cm2 at 800℃. The resistance of interface layer between Ni-YSZ anode and SDC electrolyte was the key impact on the power density.
