    摘要： Powders of respective metal elements (Mn,Co) constituting a transition metal oxide (MnCo2O4) having a spinel type crystal structure are used as a starting material. A paste containing the mixture of the powders is interposed between an air electrode and an interconnector, and with this state, a sintering is performed, whereby a bonding agent according to the present invention can be obtained. This bonding agent has a “co-continuous structure”. In the “co-continuous structure”, a thickness of an arm portion that links many base portions to one another is 0.3 to 2.5 μm. The bonding agent includes a spherical particle in which plural crystal faces are exposed to the surface, the particle having a side with a length of 1 μm or more, among the plural sides constituting the outline of the crystal face. The diameter of the particle is 5 to 80 μm.

    摘要： 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.

    摘要： 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.
