Patent ID: 7332238

Claim:
An electrochemical cell system, comprising: a housing having a first end including an air access opening and a second end having an air access opening; a metal-air cell in the housing; a plenum between the housing and the metal air cell that allows air to flow from the first end of the housing to the second end of the housing; fan in fluid communication with the metal-air cell and positioned near the first end of the housing; a first pressure-sensitive valve, positioned near the first end of the housing and the fan, in fluid communication with and responsive to the fan; and a second pressure sensitive valve, positioned near the second end of the housing, in fluid communication with and responsive to the fan, wherein the first valve, the second valve, and the fan are capable of regulating air flow to the metal air cell, and wherein when the fan is activated air is drawn into the system through the air access opening in the first end of the housing, then passes through the first valve, then passes through the plenum and contacts the metal-air cell, then passes through the second valve, and then passes through the air access opening in the second end of the housing and out of the system.
