Abstract (en)

[origin: US2005173257A1] An electrolysis cell, suitable for the electrochemical production of chlorine from aqueous solutions of hydrogen chloride. The cell preferably comprises an anode space formed from an anode, an anode frame, and a back wall, the anode frame supporting the anode, and the anode space having an inlet and an outlet for the electrolyte, a cathode space formed from a current collector. The cell further preferably comprises a cathode frame and a back wall, the cathode frame supporting the current collector and the cathode space having an inlet and an outlet for the gas, a gas diffusion electrode arranged between anode and current collector and an cation exchange membrane arranged between anode and gas diffusion electrode, wherein the gas diffusion electrode is fixed on the current collector.
