Definitions

  • the present invention concerns an electrolyzer cell with an external electrolyte circulation, in which the return of the electrolyte is effected by means of an electrically insulating intermediate member.
  • the proportion of the length of the insulating intermediate member to the cross section of its bore is so chosen that the impurities of the gases produced in the apparatus in consequence of the shunt caused by the returned electrolyte, does not exceed a definite maximum value (e. g. 1/2%)
  • a substantially greater pressure is needed than is used in present designs. This pressure, which according to experience is 1/4 and more above atmospheric, is produced by means of a pump.
  • the diagrammatic drawing shows a form of embodiment of the subject matter of the invention, Fig. 1 showing the electrolyte supply in a block of several cells and, in Fig. 2, shown in a single element on a larger scale.
  • I are the electrolyzer cells connected in series.
  • the electrolyte is fed through the distributer 2 to the intermediate member 3, which connects the cell to the distributer 2.
  • the intermediate member consists of an electrically insulating material, preferably glass, and has a narrow bore 4 in the longitudinal axis. On the one hand it is connected gas tight to the distributer by a commonly known means, and on the other hand it is carried through the wall of the cell by means of a solution tight passage.
  • the resistance L R--q9 can be raised to the required degree, q being the specio resistance of the electrolyte.
  • the resistance can be increased so much that the disturbing influence of electric shunts can be kept down to any desired amount.
  • excess pressure e. g., by means of a centrifugal pressure pump.
  • An electrolyzer cell for gas separation by water decomposition having the combination of means for externally circulating its electrolyte including a conduit for returning the electrolyte to the cell, said conduit including a tube of electrical insulation material having an extremely narrow bore with proportionately enhanced length w for producing sufciently high electrical resistance to prevent formation of the shunt currents that are responsible for causing gas impurities in the returning electrolyte passing through said tube, and pumping mechanism in said conduit for conveying the electrolyte through said tube to overcome the frictional resistance created by its said narrow bore and enhanced length.
  • An electrolyzer battery for gas separation by water decomposition consisting of a plurality of cells having the combination of means for externally circulating its electrolyte including an electrolyte distributor common to all of said cells, a tube for each of said cells joining it with said distributor consisting of electrical insulation material having an extremely narrow bore with proportionately enhanced length for producing sufficiently high electrical resistance to prevent formation of the shunt currents that are responsible for causing gas impurities in the returning electrolyte passing through said tube, and pumping mechanism in said means for conveying the electrolyte through said tubes to overcome the frictional resistances created by their said narrow bores and enhanced lengths.
