Abstract

An electrically activated diaphragm air mover for gas depolarized power supplies such as metal-air batteries and fuel cells is described utilizing an electrically activated diaphragm moving within a cell casing or enclosure. An electrically activated diaphragm connects to a control circuit mounted on a printed circuit board (PCB). The control circuit provides electrical current or charge to the electrically activated diaphragm. When electrical current or charge is applied to the electrically activated diaphragm, the diaphragm deflects in response to electrical current or charge. Movement of the diaphragm within the casing causes air to move between the interior of the casing adjacent to an air cathode and the exterior of the casing through an air opening in the casing. The air movement provides air flow to an air cathode of the cell or cells.

Claims

THAT WHICH IS CLAIMED IS
1. A ventilation system for a gas depolarized cell, comprising: a housing containing the cell; at least one passageway operable for communicating between a gas supply outside the housing and a gas electrode of the gas depolarized cell; an electrically activated diaphragm gas mover operative to cause gas to flow from the gas supply towards the gas electrode through the passageway.
2. The ventilation system of Claim 1 , wherein the gas supply is ambient air, the gas is air, and the gas electrode is an air cathode.
3. The ventilation system of Claim 1 , wherein the gas depolarized cell comprises a metal-air cell.
4. The ventilation system of Claim 1 , wherein the gas depolarized cell comprises a fuel cell.
5. The ventilation system of Claim 1 , wherein the electrically activated diaphragm air mover comprises an electrically activated diaphragm and a control circuit operable to provide electrical charge to move the diaphragm.
6. The ventilation system of Claim 5, wherein the electrically activated diaphragm is selected from the group: comprises piezoelectric ceramics, piezoelectric polymers, and electroactive polymers.
7. The ventilation system of Claim 6, wherein the electrocative polymers comprise bending actuators, ionomers, and longitudinal electrostatically driven polymers.
- 21
8. An air depolarized cell with an air cathode, comprising: an enclosure housing the air cathode; an air passageway operable for communicating between an environment and the air cathode; an electrically activated diaphragm air mover positioned within the housing and operable to alternately move air from the environment towards the air cathode, and to move air proximate to the air cathode towards the environment.
9. The air depolarized cell of Claim 8, wherein the electrically activated diaphragm air mover comprises an electrically activated diaphragm and a control circuit operable to provide electrical charge to move the diaphragm.
10. The air depolarized cell of Claim 8, wherein the electrically activated diaphragm is selected from the group: piezoelectric ceramics, piezoelectric polymers, and electroactive polymers.
11. The air depolarized cell of Claim 10, wherein the electroactive polymers comprise bending actuators, ionomers, and longitudinal electrostatically driven polymers.
12. A method for providing gas flow to a gas depolarized cell, comprising: isolating a gas depolarized cell from an environment by enclosing the cell within the enclosure; providing a gas passageway defining a gas flow path between the environment and the interior of the enclosure; positioning an electrically activated diaphragm air mover within the enclosure; and operating the electrically activated diaphragm air mover to move gas from the environment to within the enclosure and across the gas depolarized cell.
- 22
13. The method of Claim 12, wherein the gas supply is ambient air, the gas is air, and the gas electrode is an air cathode.
14. The method of Claim 12, wherein the gas depolarized cell comprises a metal-air cell.
15. The method of Claim 12, wherein the gas depolarized cell comprises a fuel cell.
16. The method of Claim 12, wherein the electrically activated diaphragm air mover comprises an electrically activated diaphragm and a control circuit operable to provide electrical charge to move the diaphragm.
17. The method of Claim 12, wherein the electrically activated diaphragm is selected from the group: piezoelectric ceramics, piezoelectric polymers, and electroactive polymers.
18. The method of Claim 17, wherein the electrostatic polymers comprise bending actuators, ionomers, and longitudinal electrostatically driven polymers.
