The electro-chemical half-cell comprises an electrode space (14) contg. an electrolyte (22), a gas space (23) and, between them, at least one gas diffusion electrode (5), acting as either anode or cathode. The gas space (23) is divided into 2 or more cascading gas pockets (20,20') one above the other and sepd. from one another. The pressure in each gas pocket (20, 20') is in equilibrium with the pressure of the electrolyte liq. column in the corresp. part of the electrode space (14) in front of the gas diffusion electrode (5). Gas can pass through the openings (11,12) to electrolyte (22). |
