Electrolysis device

Abstract

An electrolysis device is provided. The electrolysis device includes a plurality of electrolysis cells that are electrically connected in series and are arranged successively at least partly in a stack direction, where the series connection is electrically couplable to an electrical energy source. The electrolysis device also includes a cell supply unit for supplying the electrolysis cells with at least one operating material and supply conduits connected to the cell supply unit and to opposite ends of the successively arranged electrolysis cells, where a negative electric potential of the electrical energy source is electrically couplable to an electric reference potential of the cell supply unit.

         2 . The electrolysis device as claimed in  claim 1 , characterized in that a material of the supply conduits includes metal, wherein the electrolysis cells are arranged in at least two substacks, each of the at least two substacks being connected to the cell supply unit by means of at least one first supply conduit connected to the cell supply unit and to a first end of the respective substack and at least one second supply conduit connected to the cell supply unit and to a second end of the respective substack opposite the first end in the stack direction, wherein that first supply conduit which is connected to the first end of that substack that is couplable to a negative electric potential of the electrical energy source is electrically conductively connected to the cell supply unit and all other supply conduits have respective electrical insulating sections. 
     
     
         3 . The electrolysis device as claimed in  claim 2 , wherein an electrical insulation layer is arranged on the inside of the supply conduit on an insulating section end of the respective insulating section facing the respective end of the respective substack. 
     
     
         4 . The electrolysis device as claimed in  claim 3 , wherein the electrical insulation layer extends from the respective insulating section up to the respective end of the respective substack. 
     
     
         5 . The electrolysis device as claimed in  claim 3 , wherein the electrical insulation layer has a coating formed from an insulation material. 
     
     
         6 . The electrolysis device as claimed in  claim 3 , wherein the electrical insulation layer includes a corrosion-resistant metal-containing substance. 
     
     
         7 . The electrolysis device as claimed in  claim 1 , wherein the respective ends of the substacks that face the respective insulating sections are electrically insulated from the electrolysis cells. 
     
     
         8 . The electrolysis device as claimed in  claim 1 , wherein the cell supply unit is at least indirectly electrically connectable to an earthing. 
     
     
         9 . The electrolysis device as claimed in  claim 8 , where in the earthing has a sacrificial anode and/or a voltage source, by means of which an electric potential that is negative with respect to the earth potential is applicable to the cell supply unit. 
     
     
         10 . The electrolysis device as claimed in  claim 2 , wherein the substacks are connected in parallel in terms of supply to the cell supply unit.
