A process is provided for selectively plating metal onto an exposed surface of a zinc/air cell, wherein said cell comprises an anode casing inserted into a cathode casing whereby at least a portion of the anode and cathode casing is exposed to the environm...

Cathode and separator are accommodated in the cover (1). Together with the ring seal (8) these components form a pre-assembled unit for insertion and fitting into the anode cup (9). An Independent claim is included for the method of construction.

A granular zinc fuel structure for deposition in an anode container includes a hollow outer casing (20) defining an interior space filled with electrolyte (21). An interior zinc fuel structure in the form of a radial structure (24) or a honeycomb structure...

Voltaic cell element comprises a cell lid having an outer surface coated with a nickel-free copper/tin (Cu/Sn) alloy. An Independent claim is also included for an alternative voltaic cell element having a cell lid whose outer surface is coated with a nicke...

An electro-chemical device having a high catalyst utilization efficiency includes a gas diffusion electrode formed of a carbonaceous material and having a catalyst formed on at least a portion of its surface, and an electrolyte film provided in contact wit...

A composite electrode for reducing oxygen that provides the quasi four-electron reduction at selectivity of nearly 100% is provided. The composite electrode includes an electrochemical catalyst A that produces hydrogen peroxide by reducing oxygen and a cat...
