Rechargeable Metal Oxide-Hydrogen Cells.

Abstract

Electrically rechargeable nickel oxide-hydrogen cells (rated 1.0 amperehour) were fabricated using platinum catalyzed hydrogen anodes, nickel-oxide cathodes, and a two component separator system, Pellon/PKT, saturated with 30% KOH electrolyte. Also, silver oxide-hydrogen cells (rated 1.5 ampere-hours) were fabricated using similar platinum catalyzed hydrogen anodes, silver-oxide cathodes, and two different separator systems, Pellon/PKT and Dynel/cellophane/Pellon, saturated with 30% KOH electrolyte. The charge and discharge performance capabilities of the two types of electrically rechargeable cells have been measured at room temperature at current densities up to 100 milliamperes per square centimeter. The Faradaic and thermodynamic efficiencies and cycle life of the cells have been determined at various charge and discharge rates. (Author)
