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.

摘要： The invention provides a mechanically rechargeable, electrochemical metal-air battery of the type having a plurality of metal-air cells, each of the cells comprising a housing having a base, two major surfaces and two minor surfaces, defining an interior space for containing therein a metal electrode, the electrode having an electrically conductive skeletal member encompassed by a rigid static bed of active anode material and the skeletal member including a heat-conductive, plate-like portion extending above the bed of anode material. The battery further comprises air flow directing means positioned adjacent to the extending plate-like portion, for directing a flow of air towards the surfaces of the plate for the removal of heat therefrom by forced convection.
