Silver catalyzed manganese dioxide hydrogen gas absorber

Abstract From the Canadian patent

The disclosure of this application is directed to silver catalyzed manganese dioxide which is useful as a hydrogen gas absorber. The silver catalyzed manganese dioxide of this invention can be formed into a shaped article of desired configuration, inserted into an electrochemical cell such as a battery, which is subsequently sealed to absorb hydrogen, gas evolved within the cell. Absorption of hydrogen gas by the silver catalyzed manganese dioxide prevents excessive buildup of gas pressure within the sealed cell thus minimizing the possibility of rupture and complete failure of the cell.
