  • Publication number: 20160380272
    Abstract: Disclosed are a solid oxide fuel cell, a method of fabricating the same, and a tape casting apparatus for fabricating an anode. The method of fabricating the solid oxide fuel cell includes fabricating an electrolyte film sheet, a functional layer sheet, a support layer sheet, and a catalyst active layer sheet; forming a stack by sequentially stacking the electrolyte film sheet, the functional layer sheet, the support layer sheet, and the catalyst active layer sheet; fabricating an anode including the electrolyte film, the functional layer, the support layer, and the catalyst active layer by sintering the stack; and forming a cathode on the electrolyte film sheet. A catalyst content within the catalyst active layer sheet is gradually changed in a predetermined direction.

  • Patent number: 9343746
    Abstract: Embodiments of the invention are directed to SOFC with a multilayer structure comprising a porous ceramic cathode, optionally a cathodic triple phase boundary layer, a bilayer electrolyte comprising a cerium oxide comprising layer and a bismuth oxide comprising layer, an anion functional layer, and a porous ceramic anode with electrical interconnects, wherein the SOFC displays a very high power density at temperatures below 700° C. with hydrogen or hydrocarbon fuels. The low temperature conversion of chemical energy to electrical energy allows the fabrication of the fuel cells using stainless steel or other metal alloys rather than ceramic conductive oxides as the interconnects.

  • Publication number: 20130273456
    Abstract: Disclosed are a solid oxide fuel cell, a method of fabricating the same, and a tape casting apparatus for fabricating an anode. The solid oxide fuel cell includes an electrolyte film sheet, a cathode, and an anode, and the anode includes a catalyst active layer sheet for inducing a reforming reaction of the supplied fuel. The catalyst active layer sheet is formed by a tape casting method using a plurality of pieces of slurry having different catalyst contents, and the catalyst content within the catalyst active layer sheet is gradually changed in a flow direction of the fuel. In the solid oxide fuel cell, a temperature deviation of a unit cell is minimized by uniformly reforming the fuel in the flow direction of the fuel, thereby improving mechanical and chemical durability.
