Abstract

Electrolysis cell containing a liquid electrolyte and at least a gas diffusion electrode (9) with a surface in contact with the liquid electrolyte (10) and the opposite surface connected to at least two gas chambers (13), wherein said chambers are provided with rotameters (14) or equivalent devices and the connection between two subsequent chambers is provided by said rotameters or equivalent devices. Said design is characterized by the fact that it maintains a constant pressure in the chambers also with strong variations of the gas flow-rate. The chambers are further provided with at least an element (15) for discharging the liquid accumulated therein, which may comprise a bundle of hydrophilic fibers.
