Embodiment Construction

[0042] As a comparison with the prior art, an electrolyser according to the invention equipped with a helical hose as described in claim 1 is used. The electrolyzer consisted of four electrolyzer stacks, each equipped with 60 single electrolytic elements. Without stray current losses, the total voltage initially theoretically obtained under polarization also amounts to at most 250 V here, ie only the ohmic resistance of the electrolyzer under polarization is within the range of prior art electrolyzers, which The results are shown in figure 1 , which can be directly compared with the figure 2 Structural comparisons in .

[0043] figure 2 A shows the current through the electrolyzer 4 according to the invention. The electrolyzer stacks have the reference numerals 5 , 6 , 7 , 8 . Here too, the electrolyzer is supplied with a polarization current from the anode terminal, which originates from the polarization rectifier 9 .

[0044] In the case of the electrolyzer according...

Abstract

Electrolyser comprising at least one single electrolyser element which comprises at least one anode compartment with an anode, one cathode compartment with a cathode and one ion exchange membrane arranged between the anode and the cathode compartments, with the anode and / or cathode being a gas diffusion electrode. A gap is provided between the gas diffusion electrode and the ion exchange membrane, with an electrolyte inlet arranged at the upper end of the gap and an electrolyte outlet at the lower end of the gap and a gas inlet and a gas outlet. The electrolyte outlet extending into a discharge header, and the electrolyte inlet connected to an electrolyte feed tank and having an overflow, the overflow connected to the discharge header, with a coiled hose connecting the electrolyte feed tank with the electrolyte inlet and with a coiled hose connecting the overflow with the discharge header.

Description

technical field [0001] The present invention can be classified in the technical field of electrolytic devices. [0002] The invention relates to an electrolyser as characterized in the preamble of claim 1 . Background technique [0003] During electrolysis, electrical energy is converted into chemical energy. This is achieved by the decomposition of the compound induced by the action of an electric current. Solutions used as electrolytes contain both positively and negatively charged ions. Therefore, mainly acids, bases or salts are used as electrolytes. [0004] For example, in the process of producing a halogen gas from an aqueous solution of an alkali metal halide, the following reaction occurs on the anode side: [0005] (1) 4NaCl→2Cl 2 +4Na + +4e - [0006] The released alkali metal ions move to the cathode where they form lye with the hydroxide ions produced there. Additionally, hydrogen gas is formed: [0007] (2)4H 2 O+4e - →2H 2 +4OH - [0008] The ly...
