Abstract
Abstract An air manager system for a metal-air battery cell having an air a cathode, the air manager system producing a flow of air through the air manager system and battery cell and directing a first air flow adjacent to the air cathode to provide reactant air and directing a second air flow adjacent to a portion of the battery cell isolated from the air cathode to provide cooling of the battery cell, preferably near the anode. The air manager system may be used with multiple cell metal-air battery packs. Heat exchange between the isolated air flows may be facilitated, and the reactant air may be recirculated for uniform cooling.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
63 words
An air manager system for a metal-air battery cell having an air cathode, comprising: means for directing a first flow of air adjacent to the air cathode to provide reactant air, and means for directing a second flow of air adjacent to a portion of the cell isolated from the air cathode and adjacent to an anode to provide cooling of the cell.
Claim 2
Dependent Claim
63 words
An air manager system for a metal-air battery cell having an air cathode, comprising: means for directing a first flow of air adjacent to the air cathode to provide reactant air, and means for directing a second flow of air adjacent to a portion of the cell isolated from the air cathode and adjacent to an anode to provide cooling of the cell.
Claim 3
Dependent Claim
28 words
The system of claim 1, further comprising means for selectively enclosing said air cathode to terminate discharge of said cell without interrupting said second air flow for cooling.
Claim 4
Dependent Claim
35 words
The system of claim 1, wherein said first flow of air crosses said cell in a first direction, and wherein said second flow crosses said cell in a direction generally transverse to said first direction.
Claim 5
Dependent Claim
23 words
The system of claim 1, where in said anode is separated from said cooling second air flow by a highly heat conductive material.
Claim 6
Dependent Claim
26 words
The system of claim 1 further comprising means for recirculating a reactant air flow over the air cathode independent of said second flow of cooling air.
Claim 7
Dependent Claim
18 words
The system of claim 5 further comprising means for admitting fresh air into said recirculating reactant air flow.
Claim 8
Dependent Claim
18 words
The system of claim 5 further comprising a heat exchange means for cooling said recirculated reactant air flow.
Claim 9
Dependent Claim
15 words
The system of claim 5 further comprising means for humidifying said recirculating reactant air flow.
Claim 10
Dependent Claim
26 words
The system of claim 5 further comprising means for controlling the flow of recirculating reactant air to vary the amount of oxygen available to the cathode.
Claim 11
Dependent Claim
22 words
The system of claim 6 further comprising means for controlling the amount of fresh air admitted into said recirculating reactant air flow.
Claim 12
Dependent Claim
27 words
The system of claim 5 further comprising means for regulating the amount of reactant air flow to the cathode in response to oxygen demand on the battery.
