20080241058 | PROCESS FOR PRODUCING HYDROGEN WITH PERMSELECTIVE MEMBRANE REACTOR AND PERMSELECTIVE MEMBRANE REACTOR - A method for producing hydrogen including the steps of supplying a raw material gas from a gas inlet of a reactor tube; producing a gas mixture containing hydrogen, carbon monoxide, and carbon dioxide by a reforming reaction and a shift reaction; recovering, from a discharge outlet of a separator tube, hydrogen being isolated by passing through a permselective membrane into the separator tube from the gas mixture; and discharging other gas components incapable of passing through the permselective membrane from a gas outlet of the reactor. Hydrogen is produced under conditions where α defined by the following equation is in the range of 0.4 to 100: | 10-02-2008 |
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 |

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 |
20100050422 | ASSEMBLING METHOD OF SOLID OXIDE FUEL CELL - An assembling method of a solid oxide fuel cell, having a stack structure in which sheet bodies and separators are stacked in alternating layers, includes a stacking step, a sealing step, and a reduction process step. 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 |

20100190066 | REACTOR AND PRODUCING METHOD OF THE SAME - The solid oxide fuel cell has a stack structure formed by stacking sheet bodies, each of which comprises three layers of the electrolyte layer, a fuel electrode layer, an air electrode layer, and separators in alternating layers. In an air channel defined between the air electrode and the separator facing the air electrode layer, a SUS mesh made of stainless steel for electrically connecting both of them is confined. On the surface of the SUS mesh, previously by itself before the assembly of the stack structure, an Ag-plating treatment is performed and further a vacuum heat-treatment (heat-treatment under a negative pressure) is performed. | 07-29-2010 |
