REPETITION UNIT FOR A STACK OF ELECTROCHEMICAL CELLS, STACK ARRANGEMENT AND METHOD FOR PRODUCTION OF A REPETITION UNIT

摘要

The present invention relates to a repetition unit for a stack of electrochemical cells, having a cathode-electrolyte-anode unit (1) and having a first layer (2) and at least one further layer (3, 4) of an interconnector plate resting thereon, with the first layer (2) being manufactured from sheet metal and making electrical contact with the cathode-electrolyte-anode unit (1), while the at least one further layer (3, 4) is cut out in an active area, furthermore with the at least one further layer (3, 4) being composed of a formed flat material, and the first layer (2) also being formed in an edge area surrounding the active area, and with the cathode-electrolyte-anode unit (1) as well as all the said layers (2, 3, 4) being soldered to one another in the edge area. The invention also relates to a corresponding stack arrangement of electrochemical cells, and to a method for production of a repetition unit such as this.
