Abstract

The present invention relates to an arrangement for separating oxygen from an oxygen containing gas. It comprises a membrane unit (12), and an electrode unit (24). The membrane unit (12) comprises a porous substrate (20), a dense membrane (14) and at least one electrode (18), wherein the porous substrate (20) is directed towards the electrode unit (24), and wherein the electrode unit (24) comprises at least one electrode comprising at least one rotatable electrode wing (26) being at least partially electrically conductive. An arrangement according to the invention allows to separate oxygen with improved efficiency and improved convenience with respect to maintenance and noise.
