Anode supported planar solid oxide fuel cell (SOFC) with large dimension (100 x 100 x 0.5 mm(3)) has been successfully prepared by using multilayer aqueous tape casting technique and co-firing process which allow for the creation of a thin layer of dense YSZ electrolyte on NiO/YSZ porous anode support. Then the performance of a single cell with YSZ electrolyte film and La0.8Sr0.2MnO3 (LSM)+ SSZ cathode is evaluated between 700 degrees C and 800 degrees C with hydrogen as the fuel and air as the oxidant. The open circuit voltage (OCV) of 1.08 V is close to the theoretical value at 800 degrees C. The area specific resistance value is 0.79 Omega cm(2) and the maximum power density is over 0.8 W cm(-2) at 800 degrees C. In terms of the electrochemical performance, single cells fabricated from the large dimension half cell show excellent uniformity.
