The present invention relates to a CH bond cleavage apparatus using a plasma-catalyst and a method for producing hydrogen (H 2 ) and / or C 2 or higher hydrocarbons. In the present invention, in the CH bond decomposition reaction, an inert gas is used as a carrier gas and a gas separation membrane module is used to increase the methane conversion rate, and an inert gas in the discharged gas can be separated and recovered for reuse.
