摘要： A thin plate member is a thin plate member that is formed by sintering, contains a ceramic layer, and comprises a thin part having two or more types of layers laminated, each of which is made of a material having a different thermal expansion coefficient, and a thick part that is made by laminating plural layers including at least all of the layers constituting the thin part, and has a thickness greater than the thickness of the thin part. The thin part has a shape warping in the direction perpendicular to the plane of the thin plate member. By virtue of this configuration, the internal electrical resistance of the thin part can be reduced. Further, the thin plate member can be provided that is difficult to be deformed with respect to the internal stress caused by the difference in thermal expansion coefficient between layers.

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： 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 solid oxide fuel cell has a stack structure in which sheet bodies and support members are stacked in alternating layers. A space through which a fuel gas or air flows is formed between the adjacent sheet body and support member. Partitions are provided on the support member in such a manner as to stand in the space, thereby forming a “first flow F1” of gas according to the flow control effected by the partitions. Gaps are formed at the projecting ends of the partitions, thereby forming a “second flow F2” of gas which flows over the partitions and through the gaps. The ratio “gap/space height” is set to 2% to 50% inclusive.
