Abstract
A ventilation system having a micromachine air mover for a metal-air battery. The metal-air battery has a housing for enclosing at least one metal-air cell. The housing isolates the metal-air cell from the ambient atmosphere except for a pair of diffusion tubes. The micromachine air mover is an air pump that generates air flow by actuating a diaphragm which causes the diaphragm to vibrate. As a result of the vibration of the diaphragm, the pressure within the micromachine air mover's pump chamber varies and directional air flow is created through the housing and across the metal-air cell. When the micromachine air mover is not operating, the diffusion tubes provide a barrier to prevent diffusion of air through the housing.
