ELECTROLYSIS CELL OR ELECTRODE PLATE WITH GAS DIFFUSION ELECTRODE, AND METHOD FOR OPERATING SAME

The invention relates to an electrolysis cell with a gas diffusion electrode (16), to an electrode plate (16, 25) which comprises a gas diffusion electrode and can be used in such an electrolysis cell, and to a method for operating such an electrolysis cell. The gas diffusion electrode (16) separates an electrolyte chamber (13, 14) from a gas chamber (27, 28), and the gas chamber is provided witha reaction gas which is converted in the gas diffusion electrode (16). According to the invention, the gas chamber has first channels (27) and second channels (28) which run separately such that the reaction gas must pass through the gas diffusion electrode (16) laterally in order to reach the second channels (28) from the first channels (27). This can be supported by applying a pressure difference, whereby an additional setting possibility for the parameters of the ongoing electrolysis reaction is advantageously provided. The gas diffusion electrode (16) can be used together with a support element (25), which receive
