Abstract

An air manager system for a metal-air battery cell having an air cathode, the air manager system producing a flow of air through the air manager system and battery cell and directing a first air flow adjacent to the air cathode to provide reactant air and directing a second air flow adjacent to a portion of the battery cell isolated from the air cathode to provide cooling of the battery cell, preferably near the anode. The air manager system may be used with multiple cell metal-air battery packs. Heat exchange between the isolated air flows may be facilitated, and the reactant air may be recirculated for uniform cooling.
