NOVELTY - A hydrogen separation-membrane type liquefied petroleum gas reformer is provided with several reactors (6) and modifier (3). The cylindrical modifier is positioned by surrounding a combustion burner (5), and performs steam-reforming using hydrocarbon in casing (9). The reactor has hydrogen separation membrane selectively permeating hydrogen in the reformed gas. While forming height direction intermediate position of reactor, the upper-end opening portion of modifier is opened, and obstacle plate (15) is positioned at predetermined interval in opening portion of modifier.    USE - Hydrogen separation-membrane type liquefied petroleum gas reformer is used as hydrogen supply source of fuel cell and used for removing hydrogen gas from liquefied petroleum gas.    ADVANTAGE - The hydrogen separation-membrane type liquefied petroleum gas reformer provides high concentrated hydrogen gas.    DETAILED DESCRIPTION - A hydrogen separation-membrane type liquefied petroleum gas reformer is provided with several reactors and a modifier. The cylindrical modifier is positioned by surrounding a combustion burner, and performs steam reforming by using hydrocarbon as fuel in a casing. The liquefied petroleum gas is used as hydrocarbon source in the modifier. The several reactors are positioned on the concentric circle which makes center axis of modifier as axial center, and in the outer side of modifier. The reactor has hydrogen separation membrane which selectively permeates hydrogen in the hydrogen-containing reformed gas generated in the modifier. While forming height direction intermediate position of reactor, the upper-end opening portion of modifier in cylindrical shape is opened, and an obstacle plate is positioned at predetermined interval in opening portion upper side of the modifier.
