An object is to provide a fuel battery cell and a fuel battery in which gases can be supplied sufficiently to outer surfaces (main surfaces) of respective electrodes, such as a cathode. A cathode 41 of a fuel battery 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. Particularly, in order to smoothly introduce oxidizing gas to the outer surface 65, of the side surfaces of the upper layer 63, 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 (the center of the plane of the upper layer 63). |
