Technology for Making Single Cells of Anode-Supported Planar Solid Oxide Fuel cell (SOFC)

A novel process for the fabrication of a planar anode-supported solid oxide fuel cell (SOFC) of dimension up to 10 cm x 10 cm x 1.5 mm that comprises a novel Ni-YSZ functional cermet anode.

a) Development of porous anode supported half-cell consisting of a gas-tight 8 mole% yttria stabilized zirconia (YSZ) electrolyte layer over porous nickel oxide8 mole% yttria stabilized zirconia (NiO-YSZ) anode substrate; and

b) Development of porous strontium doped lanthanum manganite, La(Sr)MnO3 (LSM)-based cathode over the YSZ electrolyte surface to form the single cell.

Single cells of dimension 10 cm x 10 cm x 1.5 (± 0.05) mm is the standard size, custom size and shape is also feasible.

Operates in the temperature range 750–800°C; suitable for intermediate temperature SOFC (IT-SOFC) stack application where metallic stack components can be used
