Abstract
An air manager is disclosed which recirculates reactant air in a battery and exchanges only a minimal amount of recirculated air for ambient air that is necessary to maintain a sufficient oxygen concentration in the battery. In the air manager, the reactant air is recirculated in a defined air pathway that provides reactant air to the entire area of all the air cathodes. A catalyst element is also provided in the air manager to convert the hydrogen gas that is generated during the recharge of a metal-air battery to water vapor. The air manager is nevertheless compact and lightweight so that the resulting battery is portable.
