PURPOSE: To simplify the control system of the steam-reforming reactor, prevent the local heating of the device due to a burner, and reduce a power for an air blower by changing a methane nozzle for the burner and the burner in a conventional steam-reforming reactor into an electric heater and further changing a granular combustion catalyst into a lattice-like combustion catalyst.
CONSTITUTION: The steam-reforming reactor comprises a combustion catalyst C disposed below its center, a heating chamber 6 disposed thereabove and having a fuel-charging pipe 8, an air-charging pipe 7 and an electric heater 13 for heating air, a heat-conducting chamber 11 disposed so as to surround the heating chamber 6 and having a heat conductor 12 therein, and a steam-reforming reaction pipe 2 disposed in the heat conducting chamber 11 and having a hydrogen-separating membrane 3 disposed therein and a reformation catalyst A charged therein. A lattice-like combustion catalyst is preferably used as the combustion catalyst C.
