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 method for producing solid oxide fuel cells (SOFCs) having a cathode-electrolyte-anode unit borne by a metal substrate. The aim of the invention is to provide solid oxide fuel cells that achieve increased strength, improved temperature cycling resistance, and secure adhesion of the layers forming the cathode-electrolyte-anode unit and that can be reproducibly produced without warping. In the method according to the invention, a layer forming the anode is first applied in a wet chemical process to a surface of a porous metal substrate used as a carrier of the cathode-electrolyte-anode unit. An element which has been sintered in a gas-tight manner in advance and forms the electrolyte is then laid on or applied to said layer forming the anode in a planar manner, and in a first heat treatment up to a maximum temperature of 1250 °C, the organic components contained in the layer forming the anode are expelled, said layer is sintered, and a bond is established between the substrate and the electrolyte. Then a further layer forming the cathode is applied to the electrolyte in a wet chemical process and is sintered in a further heat treatment at temperatures below 1000 °C, and the cathode is bonded to the electrolyte.

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).

摘要： The invention relates to a functional layer for high-temperature fuel cells and to a method for the production of functional layers. The functional layer is in particular a low sintering, electrically conductive ceramic layer, which is configured between an interconnector and a cathode of a fuel cell. The functional layer according to the invention is made of a material having at least two phases. A first phase is a bismuth cobalt-containing perovskite ceramic and a second phase is a bismuth manganite and/or bismuth cobaltite (Bi-Mn-Co-O).
