Patent ID: 7223296

Claim:
A hydrogen generation system comprising: a burner unit that generates combustion gas; a tubular combustion gas passage through which the combustion gas generated by said burner unit flows; a tubular reformer having a reforming catalyst for generating a reformed gas that contains hydrogen by steam reforming from a feed material and steam using the heat from the combustion gas, the feed material containing a compound made up of at least carbon and hydrogen; and an evaporator for evaporating water from outside into steam using the heat from the combustion gas flowing through said tubular combustion gas passage, to supply the steam to said reformer, wherein: said tubular combustion gas passage is arranged to cover at least a portion of an outer surface of said reformer, said evaporator is arranged to cover at least a part of an outer peripheral side of a tubular portion of said tubular combustion gas passage, and said tubular combustion gas passage and said evaporator extend in parallel with a center axis of said reformer.
