ABSTRACT:
A rechargeable electrochemical cell is disclosed which includes both a cathode and a gas generating and consuming anode housed within a closed container. A storage volume is provided within the container for storing the gas used by the cell. A capillary mat lining material is provided throughout the gas storage volume of the cell. This lining material is in liquid transfer contact with a separator and electrolyte storage material located between the electrodes of the cell. If any electrolyte (i.e. water) of the cell is vaporized into the gas storage volume, the electrolyte will condense on the lining material and be conducted back to the separator and electrolyte storage material positioned between the electrodes.
