Abstract
A method for controlling air flow in a metal air battery includes confining at least one metal air cell within a cartridge, which has an air inlet opening and an air outlet opening, and moving air through any of a plurality of air flow paths within the cartridge. Each of the paths passes through the air inlet opening of the cartridge, through a diffusion tube, through a distributor tube, across an active surface of at least one metal air cell, and through the air outlet opening of the cartridge, wherein all of the paths are substantially equal in length.
