Component for oxygen enrichment, component stack, device for obtaining a fluid enriched with oxygen, metal-oxygen battery and motor vehicle
View Patent ↗A component for oxygen enrichment comprises at least one oxygen separation membrane formed flat with two edges running parallel to each other, the at least one oxygen separation membrane including channel side walls formed in a first side of the at least one oxygen separation membrane, running perpendicular to a surface of the at least one oxygen separation membrane and parallel to the edges of the at least one oxygen separation membrane to form at least one flow channel. A battery stack with two components for oxygen enrichment, and a battery connected to a battery stack is also disclosed.
1. A device for producing an oxygen-enriched fluid, comprising:
a component stack having at least one component pair including a first component and a second component, the first component and the second component each having at least one oxygen separation membrane formed flat with two edges running parallel to each other, the at least one oxygen separation membrane including channel side walls formed in a first side of the at least one oxygen separation membrane, running perpendicular to a surface of the at least one oxygen separation membrane and parallel to the edges of the at least one oxygen separation membrane to form at least one flow channel, the first side of the first component being a permeate side of the at least one oxygen separation membrane of the first component, the first side of the second component being a retentate side of the at least one oxygen separation membrane of the second component, the membrane of the first component and the second component each having essentially identical dimension and essentially identical shapes and the channel side walls of one of the first component and the second component are connected to an opposite side of the other of the first component and the second component such that the connected channel side walls and opposite sides of the components form at least one closed flow channel;
a fresh air supply;
a spent air drain, wherein the fresh air supply and the spent air drain are fluidically connected to opposite ends of the flow channels of the second component;
an oxygen drain configured to supply the oxygen-enriched fluid, the oxygen drain fluidically connected to ends on one side of the flow channels of the first component;
a battery air supply connected to opposite ends of the flow channels of the first component and configured to supply oxygen-depleted fluid from a battery to the flow channels of the first component;
wherein the parallel running edges of the first component are parallel to the parallel running edges of the second component.
2. The device as claimed in claim 1 , further comprising a metal-oxygen battery, wherein fluid enriched by the device is supplied to the metal-oxygen battery.
3. The device as claimed in claim 2 , further comprising a motor vehicle with the metal-oxygen battery.
