[ What is claimed is:] [1.] A galvanic cell comprising:a zinc alloy anode formed into a cap, said cap forming a substantially cup-shaped interior cavity,an alkaline electrolyte containing alkali metal hydroxide, zinc oxide, and corrosion inhibitors in aqueous solution in contact with and substantially filling said anode alloy cup-shaped interior cavity,a cathode comprising a mixture of metal oxides and conductive materials, said cathode being in direct contact with said alkaline electrolyte in the absence of a separator, said cathode structured to be substantially gas permeable and partially hydrophobic, at least on a side opposite that of the electrolyte,an insulating grommet electrically isolating said zinc alloy cap from said gas permeable cathode,
of a separator, said cathode structured to be substantially gas permeable and partially hydrophobic, at least on a side opposite that of the electrolyte,an insulating grommet electrically isolating said zinc alloy cap from said gas permeable cathode,an outer can, structurally in contact with and hol
of a separator, said cathode structured to be substantially gas permeable and partially hydrophobic, at least on a side opposite that of the electrolyte,an insulating grommet electrically isolating said zinc alloy cap from said gas permeable cathode,an outer can, structurally in contact with and holding the grommet and the cathode in place, said outer can having at least one aperture through which gas may enter in or vent from the galvanic cell wherein said gas may be electrically discharged or produced by electrically interconnecting said zinc alloy cap and said outer can, anda gas permeable hydrophobic membrane between said cathode and said gas aperture,wherein the galvanic cell is constructed to generate gas or energy or mixture thereof and wherein the galvanic cell is active when an electrical connection is made between the cap and the can.
