Abstract

The invention relates to an oxygen separation device comprising a housing, in which a membrane body separates a first chamber from a second chamber. The membrane body comprises several first channels and several second channels. The channels are arranged in the housing in such a way that their ends on one side of the membrane body are exposed to the first chamber, while their ends on the other side of the membrane body are exposed to the second chamber. In all first channels, the ends exposed to the first chamber are open, and the ends exposed to the second chamber are closed. In all second channels, the ends exposed to the first chamber are closed, and the ends exposed to the second chamber are open. The walls of the channels are formed by an oxygen transport membrane of the membrane body. The oxygen transport membrane is positioned so that the insides of the first channels are formed by the retention side of the oxygen transport membrane, and the insides of the second channels are formed by the permeation side of the oxygen transport membrane. The membrane body is held in a gas-tight manner on its outside between the ends of the channels.
