1. A portable oxygen generating device, comprising:
a reaction chamber comprising:
a catalyst that facilitates the chemical decomposition of hydrogen peroxide to oxygen and water,
an inlet for introduction of hydrogen peroxide solution into the reaction chamber, and
an outlet for release of oxygen and water vapor from the reaction chamber;
a hydrogen peroxide feed system in fluid communication with the inlet of the reaction chamber, comprising:
a hydrogen peroxide reservoir that contains aqueous hydrogen peroxide solution as a replaceable cartridge, and
a feed flow regulator that controls a rate of addition of the aqueous hydrogen peroxide solution into the reaction chamber;
a cooling system, comprising:
an inlet, in fluid communication with the outlet of the reaction chamber, for receiving the oxygen and water vapor, and
a condenser comprising two or more drains, each configured to drain water condensed from the water vapor in the cooling system;
an outlet for release of cooled oxygen gas with reduced water vapor; and
a catalytic filter situated in fluid communication between the outlet of the reaction chamber and the inlet of the cooling system, wherein the catalytic filter comprises a catalyst for the decomposition of hydrogen peroxide to oxygen and water; and
an electronic control unit that regulates a flow rate of oxygen from the device.
