1,138,830. Removing water from fuel cell electrolytes. SIEMENS A.G. 30 March, 1967 [30 March, 1966], No. 14676/67. Addition to 1,108,621. Heading H1B. Water is removed from the electrolyte circulating through a concentrator 4 during operation of the cell 1 by passing the gas through the electrolyte in the concentrator to extract the water as vapour. The gas then passes through a cooler 7 and water separator 8. The electrolyte passes through a cooler 11 before returning to the cell. As shown the gas is inert and is recirculated by fan 5. If the gas used is air (Fig. 2, not shown), after leaving separator 8 it is passed to the cell as oxidant and the surplus is vented: The carrier gas may be a rare gas, nitrogen, oxygen or air. |
