Abstract
A fluid depolarized cell containing an inert cathode with finely divided metal powder dispersed within said cathode. The metal powder such as nickel powder catalyzes the reaction of unstable decomposition products of the fluid depolarizer into more stable species. Cell safety and discharge capability are enhanced with reduced cathode passivation.
