Bipolar multi-purpose electrolytic cell for high current loads

An electrolysis cell for high current loads, comprising

• a clamping frame;
• two electrode edge plates having metal electrode sheets and supply conductor;
• and bipolar electrode plates, said bipolar electrode plates comprising:
• one electrode base body made from plastic, having at least one of cooling spaces and electrode back spaces which are machined in on one or both sides, machined-in feed and discharge lines for the electrolyte solutions and the cooling medium, metal electrode sheets which are applied to both sides of the base body and in the electrochemically active region are solid and/or perforated, electrolyte sealing frames which test on the solid metal electrode sheets and are made from elastic plastic, ion exchange membranes, which rest on the perforated metal electrode sheets and/or the electrolyte sealing frames, for separating the electrode spaces, characterized in that the electrode plates have a height-to-width ratio of 30:1 to 1.5:1, the metal electrode sheets and the electrolyte sealing frames project laterally beyond the electrode base bodies and are connected both to vertical contact rails, which are arranged on both sides at a distance of 1 to 50 mm from the electrode base bodies and, in the region of the electrolyte sealing frames, to the electrode base bodies, to form mechanically stable, bipolar electrode plates which can be fitted as independent units, the electrical insulation of two adjacent bipolar units with respect to one another being brought about by the electrolyte sealing frames, with simultaneous sealing of the electrolyte spaces when the electrode plates are clamped by means of the clamping frame as a result of the pressure wherein the electrolysis cell is a bipolar multipurpose electrolysis cell.
