Abstract
The invention relates to an electrochemical half cell (1) comprising at least one electrode space (3, 15) for receiving an electrolyte (100), a gas space (2), and at least one gas diffusion electrode (14) as anode or cathode separating the gas space (2) and electrode space (3, 15), in which the gas space (2) is subdivided into two or more superimposed gas pockets (2a, 2b), in which gas inflow and gas outflow takes place through separate openings (7) and (12a, 12b, 12c, 12d) and the pressure on the electrolyte side of the electrode (14) is compensated by an opening in the respective gas pocket (2a, 2b) for the electrolyte.
