Abstract
The present invention provides: an electrode-supporting type of gas-separation membrane module for selectively effecting the passage of a gas via an electron exchange reaction due to a coupling-material layer and gas exchange via an ion-conducting separation layer; a tubular structure of same; a production method for the tubular structure; and a hydrocarbon-reforming method using the gas-separation membrane module. The present invention is advantageous in that outstanding chemical and mechanical durability can be ensured by using a fluorite-based ion-conducting membrane which is chemically stable in CO2 and H2O atmospheres in particular, at high temperature, and in that a pure gas can be produced inexpensively since the passage of gas occurs due to an internal circuit even without applying a voltage from the outside.
