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.

System and method for the electrolysis of carbon dioxide

The present disclosure relates to electrolysis. For example, an electrolysis system for carbon dioxide utilization may include: an electrolysis cell having an anode and a cathode, where carbon dioxide reduces at the cathode to at least one hydrocarbon compound or to carbon monoxide; first and second electrolyte reservoirs; a first product gas line from the first electrolyte reservoir; a second product gas line from the second electrolyte reservoir; a first connecting line supplying electrolyte from the first electrolyte reservoir to the anode; a second connecting line taking electrolyte from the anode to the second electrolyte reservoir; a third connecting line supplying electrolyte from the second electrolyte reservoir to the cathode; a fourth connecting line taking electrolyte from the cathode off to the first electrolyte reservoir; and a pressure-equalizing connection directly connecting the first and second electrolyte reservoirs.
