A method for arranging an electrochemically active element on a fastening device which has a first holder with at least one cylindrical spacing element and has a second holder with at least one cylindrical spacing element, including: a) providing an electrochemically active element whose electrolyte side can be arranged to adjoin an electrolyte chamber and whose gas side can be arranged to adjoin a gas chamber of an electrochemical cell; b) arranging the at least one spacing element of the first holder on the gas side and arranging the at least one spacing element of the second holder on the electrolyte side of the electrochemically active element, the at least one spacing element on the electrolyte side being aligned axially with respect to the at least one spacing element on the gas side. An electrochemical cell in which an electrochemically active element is arranged on a fastening device.

Method for fastening an electrode

Various embodiments include an electrolysis cell with a housing with an anode and a gas diffusion electrode connected as cathode. The gas diffusion electrode has an electrolyte side and a gas side and separates the electrolyte space from a gas space for a reaction gas. There is a support body disposed in the gas space with a contact surface in contact with the gas diffusion electrode. The gas space comprises a first channel system and a second channel system. The first channel system and the second channel system run separately from one another and thus form two separate volumes of the gas space. The first channel system and the second channel system each have openings in the contact surface of the support body.

Electrolysis cell or electrode plate with a gas diffusion electrode

Various embodiments include a system for carbon dioxide electrolysis comprising: an anode and a cathode both connected to a voltage supply, wherein the cathode comprises a gas diffusion electrode adjoined by a gas space and a cathode space; an electrolyte circuit; a gas supply delivering carbon dioxide to the gas space; wherein the gas space has an outlet for an electrolyte, carbon dioxide, and product gases produced by electrolysis; a return connection connecting the outlet to the gas supply; and a pump for circulation of carbon dioxide and product gas in the gas space and the return connection.
