Abstract

A method of operating a mixed ionic-electronic conducting ceramic membrane having an oxidizing side and a reducing side, said method comprising a start-up phase and a production phase, for producing a gas stream, characterized in that the start-up phase comprises a step of introducing, on the oxidizing side and the reducing side of the membrane respectively, first and second gas mixtures not capable of chemically degrading the membrane; and a step of establishing a stream of oxygen through the membrane.
