LEAD-OXYGEN DC POWER SUPPLY SYSTEM HAVING A CLOSED LOOP OXYGEN AND WATER SYSTEM

An electrical power system is provided for supplying dc power to electrically motorized vehicles, emergency standby sources, and the like. A lead-oxygen battery cell used as a source of dc power includes a positive charging grid, a conventional negative electrode, a positive discharging electrode, and a Teflon membrane member coated with a catalyst contained in an atmosphere of oxygen which is admitted to the cell through the Teflon membrane. Oxygen is given off during the charging cycle and is compressed in a storage tank for reuse during each duty cycle providing a closed system wherein contamination is minimized and a long-life cycle can result.
