ABSTRACT:
An object of the invention is to provide for a metal-hydrogen cell one or more catalyzed sites for the recombination of oxygen generated at the metal electrodes with hydrogen contained in the cell.
In a metal-hydrogen cell of the type including a plurality of electrical cell units in back-to-back relationship and which may be lined with a wick, one or more catalyzed sites are provided on the inner surface of the cell. Separators disposed between the respective metal and hydrogen electrodes of each cell unit are provided with gas directing notches around their peripheries to facilitate the desired movement of gasses within the metal-hydrogen cell. Any two metal electrodes separated by a gas screen and including apertures which may be required to accommodate compression means such as bolts are provided with gas tight sealing means between the electrodes at each aperture. The sealing means may be a ring of rubber or elastomeric material which is somewhat compressible but non-reactive with other materials in the cell.
