    摘要： 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.

    摘要： The invention provides a process for preparing a gas-diffusion electrode for metal-air batteries and fuel cells of the type having a blocking layer formed from a precursor containing carbon black and particulate hydrophobic polymeric binders, comprising heating the carbon black at a temperature of about 400.degree.-1,200.degree. C. for a period of about 1-10 hours in a reducing environment, prior to the formation of the precursor, whereby hydrophilic centers in the pre-treated carbon black are minimized without increasing its corrosivity/surface area and thereby increasing the stability in concentrated KOH at high-cell operating temperatures of a blocking layer formed from the pre-treated carbon black.

    摘要： The invention provides a single pass wet fabrication process for preparing a gas diffusion electrode for metal-air batteries and fuel cells comprising:a) preparing an active-layer forming dispersion containing catalyzed carbon black, hydrophilic fluorinated polymer and particulate hydrophobic fluorinated polymer in a liquid medium;b) preparing a blocking-layer forming dispersion containing carbon black and particulate hydrophobic polymeric binders in a liquid medium;c) filtering a first of the layer forming dispersions though filtering means to deposit a first layer of damp solids mass;d) filtering a second of the layer forming dispersions through the first deposited damp solids mass before the drying or sintering of the first deposited damp solids mass in order to deposit a second layer of damp solids mass thereon in such a manner that lower components of the second layer of damp solids mass are intermixed with upper components of the first layer of deposited damp solids mass;e) drying and compressing the composite first and second layers with a conductive metal mesh incorporated therein; andf) heating the dried layers to a temperature above the sintering temperature of the hydrophobic polymer while applying pressure thereto thereby causing the polymeric materials of both layers to sinter and bond with each other and with other components of the layers.
