The invention discloses a pit strap type reforming hydrogen production device, comprising a shell (10), a catalyst plate (20), a baffle (30), a press plate (40) and a cover plate (50); the surface of the catalyst plate is coated with catalyst layers, the catalyst layers and the baffle are mounted in an interval and lamination manner, or rolling edges are arranged at two sides of the catalyst plate in a lamination manner, so a fixed gap is formed, the catalyst layers do not contact with one another, dust caused by mutual extrusion is fully avoided, the problem that hydrogen gas produced by reforming hydrogen production equipment in the prior art carries dust is solved, the pit strap type reforming hydrogen production device is mainly applied for the reforming hydrogen production equipment, particularly the site reforming hydrogen production equipment combined with a fuel battery for use.
