A depolarizer is used in a dry cell battery to prevent(minimized) the formation of hydrogend bubbles on the carbon rod of a Zinc-Carbon cell. The bubbles accurr as the battery is stored and increase its internal resistance. Once the battery is placed in service current usage will help remove the hydrogen bubbles but while bubbles are present the batteris perfromance is degraded. The depolarizer in preventing buble formation to begine with helps the battery maintain its performance specifications across its shelf life period.
