Abstract
Anode supported planar solid oxide fuel cell (SOFC) with large dimension (100 × 100 × 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 La 0.8Sr 0.2MnO 3 (LSM) + SSZ cathode is evaluated between 700 °C and 800 °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 °C. The area specific resistance value is 0.79 Ω cm 2 and the maximum power density is over 0.8 W cm − 2 at 800 °C. In terms of the electrochemical performance, single cells fabricated from the large dimension half cell show excellent uniformity.
