The invention relates to a method for producing a solid tubular oxide cell (10), in particular a fuel cell. The aim of the invention is to produce a solid tubular oxide cell, for example a solid oxide fuel cell with an inner electrode package, using few process steps and with a low reject rate in particular. This is achieved in that in a method step a) a substrate (1) is provided which (1) is made of a component for forming a gas-permeable porous ceramic material, which is inert in particular, or is made of a material which can be burned out in an ash-free manner. In a method step b) an electrode package (11) is applied onto the substrate. In a method step c) the substrate (1) provided with the electrode package (11) is introduced into a cavity of an injection molding tool such that the electrode package (11) delimits a hollow cylindrical cavity. In a method step d) an injection molding component (12) is injected into the hollow cylindrical cavity. In a method step e) the injection molded body (11, 12) is then sintered, wherein the component for forming a gas-permeable porous ceramic material is converted into a gas-permeable porous ceramic material, or the material which can be burned out in an ash-free manner is burned out. The invention further relates to a solid tubular oxide cell, in particular a solid oxide fuel cell, to the use thereof, and to a correspondingly equipped energy system.
