An improved electrochemical system, comprising (a) at least two cells in parallel electrical connection to constitute at least two cell stacks, each cell defining an anolyte chamber and a catholyte chamber, and including at least an anode electrode adjacent to the anolyte chamber, and a cathode electrode adjacent to the catholyte chamber; (b) at least one unitary one piece double electrode plate having an electrically conducting frame, the anode electrode in one of the at least two cells being supported on a first portion of the electrically conducting frame, and the cathode electrode in one of the other of the at least two cells being supported on a second portion of the electrically conducting frame spaced from the fir st portion; (c) at least two single electrode plates, each single electrode plate including an electrically conducting frame for supporting an anode electrode or a cathode electrode wherein the first and second portions of the double electrode plat e include at least opposed faces, each of the opposed faces including a substantially planar peripheral surface extending about a periphery of the supported anode and cathode electrodes, and wherein the electrically conducting frame of the single electrode plate includes opposed faces and a planar peripheral surface on each of the opposedfaces extending about a periphery of the anode or cathode supported on the single electrode plate; (d) a membrane separator; (e) an anolyte chamber forming frame member formed of a compressible elastomer and a catholyte chamber forming frame member formed of a compressible elastomer within each cell, the improvement comprising wherein the membrane separator is continuous and extends across each of the at least two cells and supported between and directly by in abutment with the catholy te chamber forming frame member and the anolyte chamber forming frame 13 member to form fluid tight seals when said electrochemical system is assembled. The system has an improved layout which minimizes the distance between adjacent cells, reduces the voltage drop between the cells and improves the electrical efficiency of the system. The system has a reduced number of component parts over the prior ar t mufti stack electrolysers and is easier to assemble. |
