| 20090029218 | Fabrication Method of Anode and Electrolyte in Solid Oxide Fuel Cell - The present invention relates to a fabrication method of a solid oxide fuel cell. The fabrication method of a fuel electrode and electrolyte of a solid oxide fuel cell (SOFC) in which a sheet cell including a fuel electrode sheet and an electrolyte sheet is positioned at an upper side of a surface of a fuel electrode pellet, includes the steps of (a) molding and heat-treating powder, in which a fuel electrode material is mixed with a pore forming agent, so as to prepare a fuel electrode pellet; (b) stacking the fuel electrode sheet containing the fuel electrode material and the electrolyte sheet containing an electrolyte material so as to prepare the sheet cell; and (c) coating an adhesive slurry containing the fuel electrode material on the sheet cell or the pellet and adhering the fuel electrode sheet of the sheet cell and the pellet and then heat-treating it. | 01-29-2009 |
| 20090035635 | Combination Structure Between Single Cell and Interconnect of Solid Oxide Fuel Cell - The present invention relates to a combination structure of a solid oxide fuel cell between an electrode and an interconnect in which the electrode and interconnect are sinter-joined to each other by using slurry in a status that a conventional current collector is excluded, thereby improving a strength and a sealing efficiency. The combination structure between a single cell and an interconnect of a solid oxide fuel cell which comprises electrolyte, and an anode and a cathode which are respectively contacted with both sides of the electrolyte; and an interconnect which are formed at both sides of the single cell and has a cathode passage for supplying air to the cathode and an anode passage for supplying fuel to the anode, is characterized by that one or both sides of the single cell are directly combined with the interconnect. | 02-05-2009 |
| 20100021779 | SOLID OXIDE FUEL CELL SYSTEM INTEGRATED WITH REFORMER - The present invention relates to a solid oxide fuel cell, in which an external reformer is integrated with a solid oxide fuel cell stack, thereby efficiently controlling heat and simplifying a system structure thereof. | 01-28-2010 |
| 20100062302 | METAL SUPPORT AND SOLID OXIDE FUEL CELL INCLUDING THE SAME - Disclosed are a metal support for a solid oxide fuel cell and the solid oxide fuel cell including the metal support. The metal support is coupled to a separator of the solid oxide fuel cell by welding and supports one surface of a unit cell comprising a fuel electrode, an air electrode, and an electrolyte layer interposed between the fuel and air electrodes, wherein the metal support is in the form of a plate and has a welding portion welded to the separator on the outer circumference thereof and a hollow portion surrounded by the welding portion to allow a fuel gas or air to flow therethrough. The use of the metal support increases the mechanical strength of the solid oxide fuel cell, resulting in improved durability and extended service life of the solid oxide fuel cell. In addition, the metal support ensures a smooth flow of the fuel gas or air, resulting in an increase in the sealing efficiency and energy production efficiency of the solid oxide fuel cell. | 03-11-2010 |

The method includes: fixedly joining a metal support to one surface of a unit cell including a fuel electrode, an air electrode and an electrolyte layer interposed between the fuel and air electrodes to fabricate a metal-supported unit cell (S | 03-11-2010 |
| 20100186220 | FABRICATION METHOD OF METAL SUPPORTED SOLID OXIDE FUEL CELL - Provided is a fabrication method of a metal supported solid oxide fuel cell (SOFC) which comprises a metal supporter, and an anode layer, an electrolyte and a cathode layer stacked in turn on the metal supporter. The fabrication method includes forming the anode layer and the electrolyte on the metal supporter; forming the green cathode layer by coating on the electrolyte a cathode slurry containing a cathode material; and in-situ sintering the green cathode layer by a normal operation of the metal supported SOFC. | 07-29-2010 |
| 20110104584 | METAL SUPPORTED SOLID OXIDE FUEL CELL - Provided is a metal supported solid oxide fuel cell in which a metal supported cell formed at one side or both sides of a unit cell is directly welded to a separation plate so as to achieve sealing therebetween, thereby preventing fuel gas and air from being leaked or mixed before reaction, and the fuel gas and air are supplied through each assigned passage so as to increase energy production efficiency and also remarkably enhance durability and sealing efficiency. The metal supported SOFC includes a unit cell | 05-05-2011 |
