Method for sealing an electrolysis cell and sealed electrolysis cell

Abstract

A method for sealing an electrolysis cell comprising an anode half-cell and a cathode half-cell formed by at least two cell elements and a sheet-like separator separating the half-cells from one another comprises providing the two cell elements and the sheet-like separator, interposing the separator between the two cell elements and interposing a layer of sealing material between each side of the separator and the two cell elements in a respective rim region of the cell elements, and sealing the electrolysis cell, wherein a force is applied to the cell elements to compress the rim regions, wherein the sealing material is an electrically isolating material and during the sealing step the state of the sealing material is changed from a liquid state to a solid state to create an adhesive bond between the cell elements and the interposed separator by the sealing material, wherein the force is relieved after the sealing material has solidified.
