Aqueous‐based tape casting is a low‐cost and environment friendly technology. In this paper, large‐area fuel electrode‐supported solid oxide cells (SOCs) were fabricated by this technology in conjunction with co‐sintering process. A 10 cm × 10 cm single cell with NiO/Zr 0.92 Y 0.08 O 2–δ fuel electrode, Zr 0.92 Y 0.08 O 2–δ electrolyte and La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3+δ /Ce 0.9 Gd 0.1 O 2+δ air electrode has been successfully developed with improved electrode microstructure and hence the cell performance with the maximum power density of 534 mW cm –2 at 850 °C with humidified H 2 as the fuel and air as the oxidant has been achieved. The optimal slurry formulations used in the fabrication of SOC were summarized for future reference purpose.
