摘要： The invention discloses a method of controlling the size distribution of electroconductive particles constituting a particulate electrode in an electrochemical cell. Particles are extracted from the particulate electrode and are subjected to elutriation, the flow of elutriating fluid being such that particles larger than a predetermined size settle against the flow of fluid, while the other particles are carried along by the elutriating fluid and are eventually returned to the electrochemical cell.
