摘要： Electrolysis cell (1), comprising
- an anode (2),
- a cathode (3),
- a membrane (4) arranged between the anode (2) and the cathode (3),
- an isolator (5) that is attached to the anode (2), the membrane (4) and the cathode (3) such that an anode chamber (6) is formed between the anode (2), the membrane (4) and the isolator (5) and a cathode chamber (7) is formed between the cathode (3), the membrane (4) and the isolator (5),
wherein the isolator (5) comprises multiple isolation elements (8,9,10), and wherein each of the isolation elements (8,9,10) is joined permanently to at least one of the other isolation elements (8,9,10).
