摘要： The invention relates to a layer structure that is formed between an interconnect and a cathode of a high-temperature fuel cell and that can be used to form a ceramic layer structure between an interconnect and a cathode. The interconnect is made of a metal alloy containing chromium. The aim of the invention is to provide a layer structure between an interconnect and a cathode of a high-temperature fuel cell, by means of which good protective function (against corrosion and against chromium evaporation), high electrical conductivity, and good thermal expansion behavior matched to the materials of an interconnect and of a cathode can be achieved. The layer structure is formed in the green state by a powdery spinel and at least one metal oxide from the group comprising CuO, NiO, CoO
x , and MnO
x as a sintering additive, and at least one powdery perovskite. Chromium is not contained in any of said chemical compounds. The fraction of contained spinel having the metal oxides as a sintering additive is reduced from the side facing the interconnect to the side facing the cathode, and the fraction of perovskite is reduced from the side facing the cathode to the side facing the interconnect.-

摘要： The invention relates to a high-temperature fuel cell system which can be operated with at least one hydrocarbon compound, preferably with methane or a gas containing methane such as natural gas or biogas. It is the object of the invention to increase the efficiency of high-temperature fuel cell systems and to allow a more flexible operation. In the system in accordance with the invention, individual fuel cells are present which are connected electrically in series and form the stacks. The stacks are flowed through after one another by fuel gas which contains hydrogen and which flows into a first stack of the system from a reformer and a suitable hydrocarbon compound is supplied via further connection lines in the flow direction of the introduced fuel gas sequentially into further stacks to the respective stack for a direct internal reforming of a hydrocarbon compound at anodes of the fuel cells of the stack and air is supplied as an oxidation means at the cathode side to the individual fuel cells of the system.

摘要： The invention relates to an arrangement of electrochemical cells and the uses of same. The electrochemical cells are arranged one above the other and are connected to each other in an electrically conductive manner. In this way, the electrochemical cells form repeating units, each of which is designed with at least one interconnector in which through-openings are formed for conducting gas, an electrochemical cell, which is formed from a cathode, an electrolyte and an anode, contact elements are formed on the anode side and the cathode side, and are arranged above one another. The surface of each of the individual planar electrochemical cells is smaller than the surface of the individual interconnectors, and the electrolytes each close flush with a plane of a surface of the respective interconnector. An individual sealing layer of a glass solder comprising a constant thickness is applied to said surface of each interconnector for sealing the gap between electrolyte and interconnector (inner joint) and the gap between through-openings for conducting gas from two adjacent interconnectors (outer joint).
