摘要： The invention relates to an electrolysis cell comprising an anode frame (26), an anode (24), a cation exchanging membrane (34), a gas diffusion electrode (32), a current collector (10), and a cathode frame (12), whereby the anode (24), the cation exchanging membrane (34), the gas diffusion electrode (32) and the current collector (10) are elastically held together so that there are no gaps between the individual components: anode (24), cation exchanging membrane (34), gas diffusion electrode (32) and current collector (10). The elastic cohesion is preferably achieved by the current collector (10) being elastically fixed to the cathode frame (12) and/or by the anode (24) being elastically fixed to the anode frame (26).

摘要： An electrochemical half cell comprises a gas diffusion electrode (22) that serves as an anode or cathode and separates an electrode space from a gas space (2). In addition, a number of gas pockets (2) are provided that are formed by the gas diffusion electrode (22) and a rear wall (5). A gas connecting channel (1) that connects two gas pockets to one another is provided through which the gas flows via a gas supply connection (3) into the gas pocket located thereabove. In order to be able to easily detach the connection, the gas supply connection (3) is accessible from the side of the gas diffusion electrode (22).

摘要： The invention concerns an electrochemical half-cell for preparing chlorine from aqueous alkali chloride solutions, comprising an electrode chamber (17) designed to contain an electrolyte. Said half-cell also comprises several gas pockets (26, 27, 28, 29) which are separated from the electrode chamber (17) by a gas-diffusing electrode (5). The invention is characterized in that said half-cell includes a support element (21), for supporting the gas pockets (26, 27, 28, 29), which is adjacent over its entire surface to the rear wall (20) of the pockets (26, 27, 28, 29) or which constitutes the rear wall (20) of said gas pockets (26, 27, 28, 29).

摘要： The invention relates to an electrochemical cell for the membrane electrolysis method, comprising at least one anode space that is provided with a metal electrode as an anode, a cathode space that is provided with a gas diffusion electrode as a cathode, and an ion exchanger membrane that is disposed between the anode space and the cathode space. The metal electrode used as an anode is immersed in an electrolyte, is provided with openings (14) in order to allow gases that are formed during operation to pass therethrough, and is optionally angled and/or bent. Said openings comprise conductor structures (12) that lead the formed gas away to the side of the metal electrode, which is located opposite the cathode.
