A complex comprising at least one hollow fiber of oxygen-transporting ceramic material, the material is either oxygen anions and electrons is a ceramic material conducts or conduct a ceramic material and an electron conducting oxygen anions ceramic or a combination of non-ceramic material, the outer surface of the hollow fiber is in contact with the same hollow fiber or another hollow fiber of the outer surface, the contact points are joined by sintering, the composite It describes the body.
Other complexes, an oxygen-transporting ceramic material, a combination of a ceramic or non-ceramic material conducts ceramic material and an electron conducting or oxygen anion is a ceramic material which conducts oxygen anions and electrons at least one hollow fiber of said oxygen-transporting ceramic material is, and a connection element for the introduction or discharge of fluids at at least one end face, wherein the connection element and the hollow fibers are joined.
The complex, to isolate oxygen from an oxygen-containing gas mixture, or for carrying out the oxidation reaction, it can be used.
