The invention relates to an arrangement of electrochemical cells and also to the uses thereof. The electrochemical cells are arranged one above another and are in electrically conducting communication with one another. In this arrangement they form repeating units which in each case are formed of at least one interconnector, in which apertures for gas passage are formed, an electrochemical cell, which is formed of a cathode, an electrolyte and an anode, and contact elements on the anode side and on the cathode side, and are arranged one above another. The area of the individual planar electrochemical cells is in each case smaller than the area of the individual interconnectors, and the electrolytes finish flush in each case with a plane of a surface of the respective interconnector. Mounted on this surface of the interconnector in each case is a single sealing ply of a glass solder with constant thickness, for sealing the gap between electrolyte and interconnector (internal joining) and the gaps between apertures for gas passage of two adjacent interconnectors (external joining).
