Abstract

A rechargeable metal-air battery having a housing, an air flow path, and at least one metal-air cell positioned within the housing. An air movement device communicates with the housing. The metal-air cell generates oxygen and hydrogen during cell charging. The air movement device creates a pulsating air flow within the air flow path for directing a flow of the generated gases.
