Electrolytic cell baffled

In a bipolar system only the end electrodes in each cell are connected to the electrical supply. Each electrode plate in the cell between the end electrodes will become an anode on one side and a cathode on the other. Current can bypass around the edges of the electrodes to flow directly through the electrolyte to the end electrodes and represents an energy efficiency loss. This can be minimised by fitting the electrodes close to the sides and baffles in the bottom of the cell. The concept is to fill the cell with cast lead anodes, which dissolve only on the one side, and pure cathode lead is deposited on the other side. The electrodes are lifted from the cell at the end of a cycle and the freshly deposited lead is separated from the residual anode. 

Baffle A non-conductive barrier inserted in a vented cell above the plate pack and used as a reference for electrolyte level it also protects the top edges of the plates from objects dropped into the vent cap hole.
