Hydrogen generation system and fuel cell system having the same

摘要

To provide a hydrogen generation system with which thermal efficiency increases, the CO level in a reformed gas stabilizes, and a supply amount of the reformed gas stabilizes, and a fuel cell system having the same. A hollow cylindrical reformer 10 surrounds a combustion chamber 17. A hollow cylindrical combustion gas passage 12 is fitted around the reformer 10. A hollow cylindrical evaporator 28 is fitted around the combustion gas passage 12. The evaporator 28 is coaxial with the combustion cylinder 17. The evaporator 28 is formed of a first evaporator section 18 and a second evaporator section 22 that is separated from the first evaporator section 18 via a partition wall 21. A plurality of openings 23 are formed in the partition wall 21.
