Abstract

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.
