A simple and mass productive extrusion technique was applied to fabricate anode-supported tubular solid oxide fuel cells (SOFCs). A standard NiO/8YSZ (nickel oxide/8 mol % yttria stabilized zirconia) cermet anode, 8YSZ electrolyte, and lanthanum strontium manganite cathode were used as the material components. Secondary electron microscopy images indicated that vacuum infiltration method successfully generated the thin electrolyte layer (about ) with a structurally effective three phase boundaries. Fabricated unit cell showed the open circuit voltage of 1.12 V without any fuel leaking problems. Electrochemical tests showed a maximum power density up to at , implying the good performance as tubular SOFCs. This study verified that the extrusion aided by vacuum infiltration process could be a promising technique for mass production of tubular SOFCs.
