PROBLEM TO BE SOLVED: To sufficiently mix a raw fuel and steam.SOLUTION: A hydrogen production apparatus 1 is provided, including a cylindrical reforming unit 6 generating a reformed gas; a feed unit 5 coaxially disposed below the reforming unit 6 and supplying a mixture gas to the reforming unit 6, and a cylindrical vaporizing unit 9 coaxially disposed in the feed unit 5, generating steam and supplying the steam to the feed unit 5. The feed unit 5 includes a mixture gas flow channel 5y formed into a cylindrical shape and allowing a mixture gas to flow through. In the mixture gas flow channel 5y, annular partitioning plates 62 are disposed in parallel as spaced from one another along the axial direction. In the adjoining partitioning plates 62a and 62b, through-holes 63a and 63b as circulation openings for the mixture gas are formed in an inner part along the radial direction of one partitioning plate 62a and in an outer part along the radial direction of the other partitioning plate 62b, respectively. Thereby, the mixture gas flows in a direction of the axial G while repeatedly turning in the radial direction. |
