Abstract
The invention relates to an electrochemical cell comprising an anode and a cathode compartment separated by a membrane, housing corresponding electrodes. The anode and the cathode compartments having external walls with frame-type flanged areas in the contact area of both compartments. The flanged areas having mounting bores marking an inner area and an outer area of the electrochemical cell a, gas-diffusion electrode resting on a support system, a porous material resting on the gas-diffusion electrode, and devices for the inlet and outlet of gas and electrolyte. At least one circumferential gasket frame is in the contact area of both compartments, between the frame-type flanged areas of the external walls of both compartments, said gasket resting on the membrane, with the porous material and the gas-diffusion electrode resting on the frame-type cathodic flanged area and the circumferential gasket frame overlapping in this area with the porous material and the gas-diffusion electrode.
