A system (10) for supplying a liquid electrolyte to cell stacks (32) arranged at a plurality of different heights comprises a plurality of constant head supply tanks (12) for containing liquid electrolyte, one for each of the different heights. Each such supply tank (12) is adapted to ensure that the surface of the liquid electrolyte is at atmospheric pressure, and to feed electrolyte to a cell stack, and incorporates an overflow duct (18) to keep the electrolyte at a constant level. For each supply tank (12) except the lowest, the overflow duct (18) supplies overflowing electrolyte to a supply tank at a lower height. The system also includes an electrolyte storage tank (20), and means (24, 26) to supply electrolyte from the storage tank (20) to the highest supply tank (12). |
