Abstract
1297698 Electrodes for fuel or metal-air cells YARDNEY INTERNATIONAL CORP 13 March, 1970 [21 March 1969] 12242/70 Heading H1B [Also in Division B1] An oxygen electrode for an air-depolarized electro-chemical system using an alkaline electrolyte comprises (i) a support, (ii) a porous active mass carried by the support and consisting of an unsintered mixture of 90-50 wt. per cent silver powder with 10-50 wt. per cent lattice-defect black copper (II) oxide powder, this mixture having a thermally cured hydrophobic binder dispersed therein, and (iii) at least one gas-permeable hydrophobic film overlying the part of the electrode surface to be contacted by air. The support used is a fluorocarbon-coated nickel screen. Specified hydrophobic binders are polytrifluorochloroethylene (T.F.E.), polytrifluoroethylene, polyvinylfluoride, polyvinylidene fluoride and polytetrafluoropropylene. The specified hydrophobic films are those prepared from uncured T.F.E. resins. The porous active mass is prepared by forming a pliable dough of the silver and copper oxide with an emulsion of uncured hydrophobic binder and then rolling the dough to form a thin foil followed by curing of the binder. The foil produced may then be affixed to the support. In the examples, the electrode is used in a zinc-air cell containing aqueous potassium hydroxide.
