ABSTRACT:
The present invention relates to an electrolysis cell for percolating a solution in order to perform a chemical reaction, such as the cathodic reduction of a metal cation.
This cell includes for example a bed of cathodically biased particles 31, a plurality of counter-electrodes 33, located at the periphery of the bed of particles and anodically biased and an additional counter-electrode 38, anodically biased and located at the center of the bed.
This arrangement allows to modify the electrode potential inside the bed, in order to avoid the unwanted electrochemical reactions.
