Abstract: The present disclosure provides a methane reforming reaction system comprising: a reaction chamber (1), a hydrogen gas separation chamber (2) and a carbon dioxide separation chamber (3). The reaction chamber (1) is used for a methane reforming reaction between methane and steam; a hydrogen permeable membrane (4) is provided between the hydrogen gas separation chamber (2) and the reaction chamber (1) and a first outlet (6) is provided on the hydrogen gas separation chamber (2) for separating hydrogen gas produced in the reaction chamber (1); a carbon dioxide permeable membrane (5) is provided between the carbon dioxide separation chamber (3) and the reaction chamber (1) and a second outlet (7) is provided on the carbon dioxide separation chamber (3) for separating carbon dioxide produced in the reaction chamber (1); wherein the hydrogen gas in the hydrogen gas separation chamber (2) has a chemical potential less than that of the hydrogen gas in the reaction chamber (1) under a chemical equilibrium state of the methane reforming reaction; and the carbon dioxide in the carbon dioxide separation chamber (3) has a chemical potential less than that of the carbon dioxide in the reaction chamber (1) under the chemical equilibrium state of the methane reforming reaction.
