Using multi-pass extrusion process, a t-ZrO 2 support tube for small tubular solid oxide fuel cell (SOFC) was fabricated. After burning out of extrusion binder, lubricant and pore former, SOFC functional layers have been coated on the tube by slurry dip coating method. The cell configuration was composed of NiO-8YSZ, 8 mol% yttria stabilized zirconia (8YSZ), Gd 0.2 Ce 0.8 O 1.9-x , (GDC) and La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 (LSCF) on the t-ZrO 2 supported tube as anode, electrolyte, interlayer and cathode, respectively. Dense microstructure of electrolyte was achieved by co-sintering. Maximum power density of 349 mW/cm 2 was obtained at 850°C using pure H 2 as fuel and stagnant air. The cell showed stability for a time period of 100 h at 850°C.
