Abstract:
1. An electrochemical cell comprising: (i) an anode half-cell with an anode, (ii) a cathode half-cell with a cathode comprising a gas diffusion electrode, (iii) an ion-exchange membrane arranged between the anode half-cell and the cathode half-cell, (iv) a gap between the gas diffusion electrode and the ion-exchange membrane, wherein the gas diffusion electrode separates the gap from a gas space, (v) an electrolyte feed inlet positioned above the gap and connected to the gap, (vi) an electrolyte drain beneath the gap, (vii) a gas inlet into the gas space, (viii) a gas outlet out of the gas space, and (ix) an electrolyte holding vessel, wherein the electrolyte holding vessel is connected to an overflow by the electrolyte feed inlet; wherein the cell is configured to provide the gap with a continuous supply of electrolyte.
