PURPOSE: To obtain an oxygen permselective film capable of preventing going out or in of water vapor and penetration of carbon dioxide by a method wherein a solution of an oxygen transporting carrier enveloping a metallic complex reversely bonded to oxygen is made into a film under a state wherein a dispersion liquid dispersed in an solute which is hydrophobic and slow in dissolving speed of carbon dioxide gels. CONSTITUTION: In an oxygen permselective film A applied to an air cell or the like equipped with a gas dispersion electrode using oxygen as an active material, the film is made by impregnating a through hole 12a of a porous layer 12 of a porous support film 1 consisting of a basic film 11 and the porous layer 12 with a fluid dispersion 2. Then, after a dispersed oxygen transporting carrier solution adsorbs oxygen selectively in the fluid dispersion 2, oxygen is dispersed in the fluid dispersion 2 to detach or attach oxygen, and oxygen is made to permeate selectively the film. The fluid dispersion 2 is adjusted by dispersing the oxygen transporting carrier solution enveloping a metallic complex unusually reversibly bonded to oxygen into a solution which is hydrophobic and slow in dissolving speed of carbon dioxide, and a film is made in a gel state by a gelling agent swelled by the solute. |
