Abstract
There is disclosed an oxygen gas permselective membrane comprising a film of a water-containable or wettable metallic oxide. The oxygen gas permselective membrane according to this invention, though being very thin, does not allow water vapor and carbon dioxide gas in air to permeate therethrough and has a great function for allowing oxygen gas to selectively permeate therethrough.
