Abstract
Abstract A combination seal and tentering means for an electrolysis cell comprising a substantially solid member interposed between at least one side of a separator of the cell and at least one electrode frame member of the cell. The substantially solid member has a first generally planar surface in contact with one side of the separator of the cell and a second uneven surface in contact with the electrode frame of the cell and a periphery defining a shoulder portion having an inside in contact with the outside surface of the electrode frame member.
