ABSTRACT:
A ventilation system for a metal-air battery having a housing for enclosing at least one metal-air cell. The housing has at least one air inlet opening and at least one air outlet opening. A fan is positioned to force air into the air inlet opening and out of the air outlet opening when the fan is turned on. The openings are sized with a length in the direction through the thickness of the housing being greater than a width in the direction perpendicular to the thickness of the housing. The openings are unobstructed and are sized to eliminate substantially the air flow into the air inlet opening and out of the air outlet opening when the fan is turned off.
