Abstract
The invention relates to electrochemical cells whereof one electrode is of a particulate type which may comprise a fluidized bed electrode, a packed bed electrode or a circulating bed electrode, an electrolyte being passed through the particulate electrode possibly for fluidizing and/or circulating the particles of the electrode. Whereas in previous cells of this kind a diaphragm has been arranged between the particulate electrode and the counterelectrode of the cell, it has been discovered that such a cell can be operated with the counterelectrode actually in contact with particles of the particulate electrode provided the material of the surface of the counterelectrode is suitably chosen. Among the materials mentioned are graphite, ruthenium oxide, lead oxide and iron oxide.
