Title: Electrolytic cells of improved fluid sealability

Abstract: An improved electrochemical system includes at least two cells. Each cell defines an anolyte chamber and a catholyte chamber, and includes at least an anode electrode adjacent to the anolyte chamber, and a cathode electrode adjacent to the catholyte chamber. At least one unitary one piece double electrode plate is provided having an electrically conducting frame. At least two single electrode plates are provided, each including an electrically conducting frame for supporting an anode electrode or a cathode electrode. A separator is between the catholyte and anolyte chambers and has at least a peripheral frame formed of a compressible elastomer. An anolyte chamber forming frame formed of a compressible elastomer and a catholyte chamber forming frame member formed of a compressible elastomer are provided within each cell. The anolyte and catholyte chamber forming frame members and the peripheral frame of the separator are compressed to form fluid tight seals when the electrochemical system is assembled. The anolyte and catholye chamber forming frame members extend beyond edges of the electronically conducting frames to allow of the peripheral frame being bonded in direct abutment with the anolyte and catholyte chamber forming frame members.
