An electrolysis cell, includes a cathode space with a cathode, an anode space with an anode, and a salt bridge space, which is arranged between the cathode and the anode, wherein the cathode space and the salt bridge space are delimited from one another by the cathode and the salt bridge space and the anode space are delimited from one another by the anode, and the cathode and the anode are formed as a gas diffusion electrode. An electrolysis plant has a corresponding electrolysis cell and a method for carries out electrochemical reactions with the electrolysis cell or electrolysis plant.

Separatorless dual GDE cell for electrochemical reactions

Various embodiments include an electrolysis cell comprising: a cathode space housing a cathode; a first ion exchange membrane including an anion exchanger and adjoining the cathode space; an anode space housing an anode; a second ion exchange membrane including a cation exchanger and adjoining the anode space; and a salt bridge space disposed between the first ion exchange membrane and the second ion exchange membrane. The cathode comprises: a gas diffusion electrode having a porous bound catalyst structure of a particulate catalyst on a support; a coating of a particulate catalyst on the first and/or second ion exchange membrane; and a porous conductive support impregnated with a catalyst.

Two-membrane construction for electrochemically reducing CO2

An electrode, which includes at least one tetragonally crystallized compound containing at least one element selected from the group of Cu and Ag, the crystal lattice of the compound being of the space group I4/amd type. An electrolysis cell includes the electrode.

Hydrocarbon-selective electrode

The present disclosure relates to electrolysis systems and methods. The teachings thereof may be embodied in methods and systems for the utilization of carbon dioxide and production of carbon monoxide. For example, a method may include: passing an electrolyte and carbon dioxide in front of a cathode through a cathode chamber; and removing electrolysis byproducts from an electrolyte/electrolysis product mixture using a catalytic filter system. The cathode may include material to reduce carbon dioxide. The process may generate a hydrocarbon compound or carbon monoxide as the electrolysis product and a formate as an electrolysis byproduct. The filter system may include a functionalized complex or a functionalized support material which catalyzes a cleavage reaction of formates (a) to hydrogen and carbon dioxide, or (b) to water and carbon monoxide.
