The apparatus includes a container which allows the wet membrane, or a series of membranes separated by plastic sheets to lay flat inside the container protected by a plastic sheet. The container has a roller tension bar across one end which allows each membrane to be pulled out of the container directly into the area between the anode and cathode of the cell for mounting into place. |
