    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.

    摘要： A thin plate member has a uniform thickness of not less than 5 μm and not more than 100 μm, includes at least a ceramic sheet, formed by sintering. The thin plate member has plural convex portions protruding from one plane P of the thin plate member, and plural concave portions caved in from the plane P. Accordingly, the deflection amount obtained when the thin plate member is supported at a predetermined support section of the thin plate member in a direction orthogonal to the plane P is smaller than the deflection amount of a thin plate member that is flat without having convex and concave portions. Therefore, a thin plate member which is difficult to be deformed is provided.

    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： In a fuel cell, perimetric portions of each sheet body, an upper support member, and a lower support member are sealed against one another by a seal including first and second seal portions. The first seal portion is of glass having a softening point lower than a working temperature of the reactor and seals against the upper surface of the perimetric portion of the sheet body and the lower surface of the perimetric portion of the upper support member as well as the lower surface of the perimetric portion of the sheet body and the upper surface of the perimetric portion of the lower support member. The second seal portion is of glass having a softening point higher than the working temperature and seals against the lower side end and upper side end of the perimetric portions of the upper and lower support members, respectively.

    摘要： A device includes a ceramic thin plate member including a fired ceramic sheet; and a metal thin plate member having an outer shape larger than that of the ceramic thin plate member. An outer circumferential portion of the ceramic thin plate member is joined to the metal thin plate member. The ceramic thin plate member has through holes and a plurality of crease portions. Each crease portion has a ridge portion whose crest continuously extends from a joint portion between the ceramic thin plate member and the metal thin plate member toward an outer circumferential portion of the metal thin plate member. Since thermal stress due to a difference in thermal expansion between the metal thin plate member and the ceramic thin plate member can be relaxed through expansion of the crease portions, the ceramic thin plate member does not deform.

    摘要： A thin plate member 10 includes an electrolyte layer 11, a fuel electrode layer 12 laminated and formed on the upper surface of the electrolyte layer 11 and having a thermal expansion coefficient greater than that of the electrolyte layer 11, and an air electrode layer 13 laminated and formed on the lower surface of the electrolyte layer 11. Further, a porous layer 14 made of a porous insulating member having a thermal expansion coefficient smaller than that of the fuel electrode layer 12 and a terminal 15 for taking generated power to the outside are laminated and formed extremely uniformly on the upper surface of the fuel electrode layer 12 in plan view. As a result, the warp of the whole thin plate member 10 with respect to the internal stress caused by the difference in the thermal expansion coefficient between layers can be suppressed. Further, since the porous layer 14 interposed between the fuel gas flow path and the fuel electrode layer 12 is made of a porous member, the circulation of the fuel gas to the upper surface of the fuel electrode layer 12 is difficult to be hindered, whereby the permeability of the fuel gas can be secured.
