摘要： A plate assembly includes a first plate and a second plate positioned adjacent to one another. The first plate includes a first sealing member formed thereon. The second plate includes a second sealing member formed thereon. The first sealing member includes a first end surface and first opposing sides extending from the first end surface. The second sealing member includes a second end surface and second opposing sides extending from the second end surface. The first and second sealing members are offset relative to one another by a first offset distance (D1) in a first longitudinal direction. By varying the sealing member's base width periodically, a greater sealing force is achieved. By offsetting alignment of pairs of sealing members along the seal path, uniform pressure along the seal path is achieved.

摘要： A fuel cell and a fuel cell stack. A cathode (41) of a fuel cell (3) assumes the form of a square plate and is composed of a lower layer (61) on a side toward a solid oxide body (37), and an upper layer (63) which covers the outer surface of the lower layer (61). The lower layer (61) is square in planar shape, and its four side surfaces stand upright in its thickness direction. The upper layer (63) is square in planar shape and has a square main surface (outer surface) (65) which faces outward in its thickness direction, and side surfaces at its four sides. Opposite side surfaces (67) and (69) residing in a flow path extending between an oxidizing gas inlet side and an oxidizing gas outlet side are flat and inclined toward the center of the outer surface (65).

摘要： Provided is a fuel cell as a fired body including a porous plate-like support substrate having a gas flow path formed therein, and a power generation element part provided on a principal surface of the support substrate, the power generation element part including at least a fuel electrode, a solid electrolyte, and an air electrode laminated in this order. The generation of cracks in the support substrate has a strong correlation with a “surface roughness of a wall surface of a gas flow” of the fuel cell in a state of a reductant. When the surface roughness of the wall surface of the gas flow path is 0.16 to 5.2 in terms of an arithmetic average roughness Ra in a state in which the fuel cell is a reductant that has been subjected to heat treatment in a reducing atmosphere, the generation of the cracks can be suppressed.
