| 20080292932 | SOLID OXIDE FUEL CELL - A fuel cell has a stack structure in which fired sheet bodies (laminates each including a fuel electrode layer, a solid electrolyte layer, and an air electrode layer) and support members for supporting the sheet bodies are stacked in alternating layers. Each of the sheet bodies is warped downward (toward an air-electrode-layer side). Because of a magnitude relationship of thermal expansion coefficient among the layers in the sheet body and that between the support member and the sheet body, a warp height gradually lessens in the course of temperature rise at start-up. However, even when a working temperature (800° C. or the like) is reached, the sheet bodies are still warped downward. By virtue of presence of the warp, the sheet bodies become unlikely to be deformed at the working temperature. | 11-27-2008 |

| 20090081514 | REACTOR AND SOLID OXIDE FUEL CELL - In a solid oxide fuel cell, air supplied from the outside through an air supply port Pain firstly flows through an air supply channel Hain in the downward direction to flow in air channels Sa. The air flowing into the air channels Sa flows through the air channels Sa in the lateral direction to flow out to an air discharge channel Haout. The air flowing out to the air discharge channel Haout flows through the air discharge channel Haout in the upward direction to be discharged to the outside from an air discharge port Paout. When a pressure loss ratio ΔPc/ΔPm, which is a ratio of a pressure loss ΔPc of air generated in the air channel Sa to the pressure loss ΔPm of air generated in the air supply channel Hain (or the air discharge channel Haout) during the operation of a fuel cell (at working temperature), is within 1 to 2500, the flow rate of the air flowing into each air channel can be equalized as much as possible, thereby being capable of preventing the reduction in the output. | 03-26-2009 |
| 20090169940 | REACTOR - A fuel cell employs a stack structure in which a plurality of sheet bodies and a plurality of separators are stacked and joined together in alternating layers. Chemical reactions occur in the sheet bodies. The separators separate, from each other, two kinds of gasses (air and fuel gas) which are necessary for the chemical reactions. The plurality of separators consist of high-rigidity separator(s), and ordinary separators, which are lower in rigidity than the high-rigidity separator. This configuration reliably suppresses the occurrence of “separation of a joint region” attributable to “stress concentration caused by increase in the number of the stacked separators. | 07-02-2009 |
| 20090191440 | SOLID OXIDE FUEL CELL - A solid oxide fuel cell has a stack structure in which sheet bodies and separators for separating air and fuel gas are stacked in alternating layers. Each of the sheet bodies includes an electrolyte layer, a fuel electrode layer formed on the upper surface of the electrolyte layer, and an air electrode layer formed on the lower surface of the electrolyte layer, wherein these layers are stacked and fired in such a manner that the electrolyte layer is sandwiched between the fuel electrode layer and the air electrode layer. The thickness of the electrolyte layer is 0.3 μm or more and 5 μm or less, and the electrolyte layer is composed of a single particle of YSZ in the thickness direction. Thus, the electrolyte layer is extremely thin, and further, the grain boundary in the thickness direction is small. Accordingly, the IR loss (electric resistance) of the electrolyte layer can remarkably be reduced. | 07-30-2009 |

In the sealing step, a laminate in which a crystallized glass material is interposed between the perimetric portions adjacent to each other is heated, so that the crystallization rate of the crystallized glass is increased to 0 to 50%. Accordingly, the perimetric portions adjacent to each other are integrated and sealed, and a room for glass softening is left. In the reduction process step, the laminate is heated, and a reduction gas is supplied into a fuel channel, whereby the reduction process is performed to the fuel electrode layer, and the crystallization rate is increased to 70 to 100%. Thus, the assembly of the fuel cell is completed. | 03-04-2010 |

| 20100330457 | SOLID OXIDE FUEL CELL - A stacked body for a solid oxide fuel cell includes a fuel electrode layer having a fuel channel formed therein, an electrolyte layer, and an air electrode layer. The fuel electrode layer contains zircon. With this, the degree of the contraction of the fuel electrode layer, which is produced when a reduction process is executed to the fuel electrode layer in order to allow the fuel electrode layer to function as an anode electrode, can be suppressed. When a reduction process is performed to the fuel channel in the assembled stack structure that includes plural stacked bodies and plural interconnectors, the present invention can prevent the occurrence of the situation in which the electrical connection is lost at a part of the electrically connected portion between the stacked body and the interconnector due to the contraction. | 12-30-2010 |
