Abstract
A bi-directional air exchanger for a metal-air battery having a housing. The air exchanger includes an ambient air passageway for a first flow of air in a first direction, a battery exhaust passageway for a second flow of air in a second direction, and one or more membranes. The ambient air passageway and the battery exhaust passageway are separated within the housing by the one or more membranes such that the first and the second flows of air are in fluid communication with one another for the exchange of humidity.
