Abstract
A method for maximizing the effective life and utilization of CO.sub.2 -absorbent material in a scrubber system for removing carbon dioxide from an air inflow to a metal-air battery or fuel cell comprises providing, in such a battery, a housing including a gas inlet, a gas outlet, and at least one removable, gas-permeable container containing a CO.sub.2 -absorbent material, the container being positioned across the flow path of gas entering said inlet and exiting said outlet. After a predetermined utilization of the system, the at least one removable, gas-permeable container is removed therefrom and spent CO.sub.2 -absorbent material from the container is regenerated for reuse in the scrubber system, the regeneration including at least periodically removing accumulated Group 1a metal carbonate deposits.
