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

摘要： A method for producing gas diffusion electrodes, in particular for use in electrolysis cells, as well as electrodes and their uses are described. A method of the present invention involves first, a sheet-like structure is produced by means of a pair of rolls by rolling a powder mixture containing at least one catalyst or a catalyst mixture and a binder, and then the sheet-like structure is connected to an electrically conductive catalyst support by rolling by means of a pair of rolls. In one embodiment the clamping force of the rolls is preferably kept constant in the range from 0.2 kN/cm to 15 kN/cm.
