Abstract
A cylindrical metal-air cell has a cylindrical housing, an axially extending cylindrical air cathode adjacent an interior surface of the housing, and a plurality of elongate plenums defined between the oxygen electrode and the interior surface of the housing. Isolating passageway are positioned between the ambient environment and each of the plenums, and an air moving device is operable to force air through the isolating passageways and into at least one of the plenums. The air moving device may be a micromachined blower controlled by a circuit integrated into the housing of the blower.
Claims13
A metal-air power supply, comprising:
- a generally cylindrical housing having opposite ends and extending in an axial direction between the opposite ends;
- an oxygen electrode that extends in the axial direction and is adjacent an interior surface of the housing;
- a plurality of elongate plenums defined between the oxygen electrode and the interior surface of the housing;
- a plurality of isolating passageways that at least partially define a communication path between the environment exterior to the housing and each of the plenums;
- and
- an air moving device operable when on for forcing air through the isolating passageways and into the plenums,
- wherein the isolating passageways are operable to restrict airflow through the isolating passageways while the isolating passageways are unsealed and the air moving device is not forcing air through the isolating passageways.
