摘要： Various embodiments include a system for carbon dioxide electrolysis comprising: an electrolysis cell having an anode and a cathode comprising a gas diffusion electrode adjoined by a gas space and a cathode space; an electrolyte circuit adjoining the electrolysis cell; a gas supply for supplying carbon dioxide-containing gas to the gas space, the gas space including an electrolyte outlet; and a shutoff device for the electrolyte outlet, wherein the shutoff device opens when a pressure differential between the gas space and the cathode space exceeds a threshold value.

摘要： Various embodiments may include a system for carbon dioxide electrolysis comprising: an anode; a cathode including a gas diffusion electrode adjoined by a gas space and a cathode space; an electrolyte circuit; a gas supply delivering carbon dioxide-containing gas to the gas space, wherein the gas space includes an outlet for an electrolyte, carbon dioxide, and product gases resulting from the electrolysis; and a throttle connecting the outlet to the electrolyte circuit, wherein the throttle creates a predefined pressure differential between the gas space and the cathode space when a mixture of product gases and liquid electrolyte flows through the throttle.

摘要： 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.
