This paper describes a simple and reliable method of fabricating an anode-side, substrate-supported (AS-SS) planar cell constructed of a porous 3YSZ support and thin, selective-area layers of NiO/YSZ anode, 8YSZ electrolyte, and LSM cathode sequentially coated on the support. Extension of triple phase boundary (TBP) at the electrode/electrolyte interfaces was done by coating SDC thin films within the pores of the electrodes using a sol-gel technique to improve performance of the cell. An anode-supported (AS) planar cell was produced using the same procedure and technique, thus expected to have identical cell components except for the anode morphology. The AS-SS planar cell exhibited a maximum power density of 0.85 Wcm−2 which is higher than the 0.60 Wcm−2 achieved from the AS planar cell at 800°C in humidified hydrogen versus air.
