ABSTRACT OF THE DISCLOSURE Method and apparatus for installation of a membrane to a finger type electrolytic cell are provided. The method comprises covering the horizontal surfaces of a cathode of the cell, not opposing an anode with a membrane installation frame having a collar, positioning the membrane substantially parallel to the vertical surfaces of the cathode, and installing and securing the membrane to the collar by a mechanical securing means. Not only is efficiency of installation for the membrane to the electrolytic cell greatly improved, but also, in the case of an ion exchange membrane, an alkali metal hydroxide liquor containing hardly any alkali metal chloride is produced. According to the invention, a conventional asbestos diaphragm finger type electrolytic cell is advantageously converted to an ion exchange membrane electrolytic cell.
