In this paper anode support was fabricated by tape casting method using SDC-50 wt.% NiO slurry, then printed the Ce0.8Sm0.2O1.9 (SDC) electrolyte on the green piece which is cut out from the dried slurry piece. After at 90 °C drying for 14 h and co-sintered at 1350 °C for 10 h, get the Φ70 mm anode support and electrolyte planar bilayer. Based on the observation of photos and scanning electron microscopy (SEM) indicated that bilayer owns the flat anode support substrate, and the highly dense, crack free electrolyte film which is 12 μm in thickness. Small disks which were cut out from the Φ70 mm bilayer structure electrochemically were examined in a single button-cell mode incorporating a SDC-60 wt.% La0.5Sr0.5Co0.8Fe0.2O3 composite cathode. The single cell was tested at 450 °C∼600 °C, an open-circuit voltage (OCV) of 0.94 V and the maximum power density of 797 mV cm−2 achieved with dry hydrogen as fuel gas and air as oxidant gas at 600 °C.
► Anode support was fabricated by tape casting method using SDC-50wt.%NiO slurry.
► Anode film is about 12 μm in thickness. Cathode is Ba0.5Sr0.5Co0.8Fe0.2O3/SDC.
► The single cell’ achieved 0.32 A·cm−2·at 0.6 V with hydrogen and air at 600 °C.
