Abstract
An improved gas permeable hydrophobic electrode structure and procedures for making it are provided. The electrode structure comprises an electrically conductive metal current collecting grid and catalyst substrate, for example, nickel. A manganese dioxide catalyst is deposited on, and is adhered to, both side faces of the grid. Such manganese dioxide is one which has been deposited in situ on a suitable substrate, for example, activated carbon or sintered nickel, and is bound together within the selected substrate by means of a fluorocarbon polymer, for example, polytetrafluoroethylene. A hydrophobic semipermeable membrane, for example, a fibrous polytetrafluoroethylene membrane or a microporous polypropylene membrane, is secured on one side of the coated nickel grid. The catalyst of manganese dioxide, formed in situ, for example, by specifically recited techniques on the above-noted selected substrate is bound together within the pore structure of the selected substrate by means of a fluorocarbon polymer, for example, polytetrafluoroethylene.
