NOVELTY - The method comprises constructing a portion of a fixed oxide fuel cell element (2) by applying a first layer portion with predetermined dimensions of a particulate ceramic material in a predetermined area on a base layer, heating the layer portion by a heat source such that particles of the ceramic material interconnect within predesignated dimensions and applying a second layer portion of the particulate ceramic material on the base layer comprising the first layer portion. The application step of the layer portion comprises providing a powder bed made of ceramic particles on the base layer.    USE - The method is useful for manufacturing a fixed oxide fuel cell element by layered structure.    ADVANTAGE - The method is capable of energy efficiently and rapidly manufacturing the one-piece fixed oxide fuel cell element with high compactness and low weight in an environmental friendly manner.    DETAILED DESCRIPTION - The method comprises constructing a portion of a fixed oxide fuel cell element (2) by applying a first layer portion with predetermined dimensions of a particulate ceramic material in a predetermined area on a base layer, heating the layer portion by a heat source such that particles of the ceramic material interconnect within predesignated dimensions and applying a second layer portion of the particulate ceramic material on the base layer comprising the first layer portion. The application step of the layer portion comprises providing a powder bed made of ceramic particles on the base layer, sintering the particles in a subregion of the powder bed with predesignated dimensions by the heat source in such a manner that particles interconnect within predesignated dimensions, cooling, supplying ceramic particles on the predetermined area on the base layer by nozzles, and sintering the particles by the heat source in such a manner that the particles interconnect within predesignated dimensions and cooling the particles. The heat source is movable. The application of the layer portions is performed by a continuous or pulse-type power output of the heat source till reaching the predetermined dimension of the layer portion. The fixed oxide fuel cell element is prepared: in such a manner that by successive application of a sequence of layer portions of different compositions made of ceramic material, one-piece gas element with different ceramic materials results; and rotationally around a center axis, where an aperture is formed directly along the central axis. An arrangement of spaced annular or ring segment-shaped anodes (22) and a cathode (24) with an intermediate electrolyte (26) is produced. The arrangement is enclosed by a radial inner casing and a radial outer casing, where the anode consists of a first composition made of the ceramic material, the cathode consists of a second composition made of the ceramic material and the casings consist of a third composition made of the ceramic material. The anode of the first composition is connected with the nearest axially spaced cathode of the second composition on a support structure, which is made of a conductive material, where the corresponding anode and the respective cathode do not enclose common electrolyte. A supporting structure is arranged at end regions of the fuel cell element to provide an electrically conductive connection to a lid. The layer portions having the anode, the electrolyte, the cathode and an air channel (28) or a channel structure are lined up in a radial extension and in an axial extension. The ring-shaped or ring segment-shaped layer portions are surrounded by the aperture. A thickness of the layer portion is 50-100 mu m.
