Abstract

The characteristics and performance of the anode-supported tubular cells with thin and dense Ba(Zr0.1Ce0.7Y0.2)O 3-δ (BZCY) electrolyte was investigated. The fine BZCY powder was prepared by a co-precipitation method. The Ni-BZCY anode tube was fabricated by an extrusion process. Ni-BZCY/BZCY nanocomposite slurry was coated on the anode tube as an anode fuctional layer (AFL) by using the dip-coating method. The BZCY electrolyte and LSCF-BZCY cathode was coated by vacuum slurry coating and dip-coating method, respectively. The anode tube had 0.381 μm in pore size (porosity: 34%). The impedance analysis of the tubular BZCY cells was conducted under open circuit condition. The ohmic resistance and the polarization resistance of the BZCY electrolyte were about 0.78 Ω cm 2 and 0.035 Ω cm2 at 700 C, respectively. The performance was measured under humidified H2 (5% H2O) atmosphere at 600-700 C. The maximum power density of the tubular BZCY cell was about 0.5 Wcm-2 at 700 C.
