    摘要： The invention relates to stackable high temperature fuel cells which may be combined to give so-called fuel cell stacks and electrically connected to each other in parallel, or in series. According to the invention, said high temperature fuel cells form an electrically-conducting connection between a cathode and an interconnector, which has a sufficiently high electrical conductivity and a chemical and mechanical resistance and stability sufficient enough for temperatures above 800 °C and for the oxidising atmosphere present for the operation of fuel cells. Said high temperature fuel cells have a fuel supply connection on the anode side and an oxidising agent supply connection on the cathode side. The cathode is electrically connected to an interconnector by means of at least one spring elastic contact element. The spring elastic contact element comprises one or more regions exerting a pressure force on regions of the interconnector, whereby said contact element is made form an electrically-conducting ceramic material.

    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).
