Abstract

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.

First claim

1 . A component for oxygen enrichment, comprising:
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.

2 . The component as claimed in claim 1 , wherein the first side is a permeate side of the membrane.

3 . The component as claimed in claim 1 , wherein the first side is a retentate side of the membrane.

4 . A component stack, comprising:
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 permate 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.

5 . The component stack as claimed in claim 4 , wherein the membrane of the first component and the membrane of the second component have essentially a quartic discrete rotationally symmetrical shape and the first component the second component are arranged such that parallel running edges of the first component are perpendicular to parallel running edges of the second component.

6 . The component stack as claimed in claim 4 , wherein the parallel running edges of the first component are parallel to the parallel running edges of the second component.

7 . 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 permate 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; an oxygen drain configured to supply the oxygen-enriched fluid, wherein the fresh air supply and the spent air drain are fluidically connected to opposite ends of the flow channels of the second component, and the oxygen drain is fluidically connected to ends on one side of the flow channels of the first component.

8 . The device as claimed in claim 7 , further comprising a battery air supply connected to opposite ends of the flow channels of the first component and is configured to supply oxygen-depleted fluid from a battery to the flow channels of the first component.

9 . The device as claimed in claim 7 , further comprising a metal-oxygen battery, wherein fluid enriched by the device is supplied to the metal-oxygen battery.

10 . The device as claimed in claim 9 , further comprising a motor vehicle with the metal-oxygen battery.
