Electrochemical cell

The present invention pertains to an electrochemical cell (1) comprising: - an anolyte space with an anode (11); - a catholyte space with a cathode (12); and - a separator disc (2) separating the anolyte space from the catholyte space; wherein the anolyte space and/or the catholyte space comprise at least one wall (2) which is rotatable about an axis of rotation crossing the separator disc, wherein the electrochemical cell comprises at least one stator (6, 7) in the anolyte space and/or the catholyte space
