Abstract
A seal for preventing passage of fluid through an opening in an electrolytic cell wall through which a conductor for carrying electricity to or from a cell electrode passes includes as elements thereof a portion of the cell wall opening which is tapered so as to be larger at the outer part of the wall than at the inner part, silicone rubber in the narrower tapered opening part, an electrolyte-resistant rubber, such as neoprene, in the wider tapered opening part and means for pressing such rubber against the silicone rubber so as to help seal the silicone rubber against the tapered cell wall and the conductor. Preferably, the seal is a gas-tight seal and prevents hydrogen from escaping into the atmosphere from the catholyte compartment of an electrolytic cell for the electrolysis of brine. Such a cell is preferably an externally connected (by conductors) bipolar cell but the invention is adaptable for use in sealing off openings in the cell walls between the electrolyte compartments of internally connected bipolar cells and for monopolar electrolytic cells too.
