The present invention relates to a gas separation membrane for separating a target gas species from a mixture of gas species, the membrane comprising: (i) a porous substrate having a first and second surface region between which the mixture of gas species will flow; (ii) a sealing polymer layer of different composition to the porous substrate that (a) forms a continuous coating across the second surface region of the substrate, and (b) is permeable to the mixture of gas species; and (iii) a selective polymer layer in the form of a cross linked macromolecular film that (a) is located on and covalently coupled to the sealing polymer layer, and (b) has a higher permeability to the target gas species relative to other gas species present in the mixture of gas species that is to be subjected to separation.

A reforming device (1) is provided with, on one end side of a chamber (2), a gas supply part (3) and, on the other end side of the chamber (2), a gas discharge part (4). A support part (5) for supporting a porous material (10) is provided between the gas supply part (3) and the gas discharge part (4) inside the chamber (4). Then, the unsaturated hydrocarbon gas of an unsaturated hydrocarbon supply device (31) and the ozone gas of an ozone generation device (32) are supplied into the chamber (2) via the gas supply part (3) so as to reform the outer-peripheral-side surface and the inner side surface of the porous material (10) accommodated inside the chamber (2). The gas inside the chamber (2) is sucked by the gas discharge part (4) and discharged to the outside of the chamber (2).
