Abstract
A fuel cell and a fuel cell stack. A cathode () of a fuel cell () assumes the form of a square plate and is composed of a lower layer () on a side toward a solid oxide body (), and an upper layer () which covers the outer surface of the lower layer (). The lower layer () is square in planar shape, and its four side surfaces stand upright in its thickness direction. The upper layer () is square in planar shape and has a square main surface (outer surface) () which faces outward in its thickness direction, and side surfaces at its four sides. Opposite side surfaces () and () 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 ().
