A ventilation system for metal-air battery cells having collapsible isolation passageways for controlling ambient airflow to the oxygen electrode of the metal-air battery. The ventilation system has at least one inlet isolation passageway and at least one outlet isolation passageway. The isolation passageways normally remain in a collapsed position to restrict airflow when an air mover is turned off. The isolation passageways may be configured into an expanded position in response to airflow generated by the air mover. In the expanded position, the inlet isolation passageway permits ambient air to flow across the oxygen electrode and the outlet isolation passageway permits oxygen depleted air to be expelled.

1. A ventilation system for a metal-air battery comprising:a housing for enclosing at least one metal-air cell; a ventilation passageway having a collapsible resilient portion, said ventilation passageway at least partially defining a communication path between the exterior and interior of said housing, said resilient portion biased to normally remain in a collapsed position to restrict airflow therethrough, said passageway remaining unsealed when said resilient portion is in said collapsed position, and said resilient portion being expandable into an expanded position; and means for expanding said resilient portion into said expanded position such that enhanced airflow is permitted through said ventilation passageway when said resilient portion is in said expanded position.
