A number of embodiments of fuel cells including a storage battery which can intermittently supply electrical power to a load. In such embodiment, water vapor generated from the operation of the fuel cell is condensed, purified and returned to the storage battery to replace the water consumed from the electrolyte from the battery operation. The water vapor is reclaimed by a series of condensers and is returned to a purifier. In some embodiments the reclaimed water vapor is delivered to the battery by an intermittently operated pump while in other embodiments the water vapor is returned by a continuously operated pump through some form of overflow device to ensure against dilution of the electrolyte in the battery. |
