Definitions

  • Electrolysis converts electrical energy into chemical energy. This is achieved by the decomposition of a chemical compound under the action of an electric current.
  • the solution used as electrolyte contains positively and negatively charged ions. Accordingly, the main electrolytes used are acids, bases or salts.
  • the pressure of the electrolyte in the channel-shaped electrolyte inlet increases above the gap.
  • the pressure in the electrolyte inlet can be adjusted. As the pressure increases, more electrolyte can therefore be passed through the gap and the flow velocity in the gap can be selectively varied.
  • the pressure in the electrolyte inlet can be adjusted in a targeted manner.
  • an electrolyzer 1 is considered below as an example, as in FIG Fig. 1 A , which consists of 160 individual electrolysis elements, which are arranged in two electrolyzer stacks 2 and 3.
  • a polarization current of 27 A is fed on the anode side, so that a total voltage of theoretically about 250 V is obtained without stray current losses.
  • An electrical model which takes into account the different ohmic resistances of the elemental components and the electrolytes as well as the corresponding electrochemical equations, can be used to calculate the current intensity per element.
  • the results are in Fig. 1 B reproduced, which maps the current in the element relative to the element number, ie the position in the electrolyzer.
