PROBLEM TO BE SOLVED: To provide a hydrogen generation apparatus capable of being operated stably over a long period of time by preventing a partition wall covering a part of an evaporator from being broken, even if there is thermal expansion and contraction by repeated operation and stopping.SOLUTION: In a heater (inner cylinder 1), combustion gas is generated by burning a gaseous mixture of fuel and air in a combustion part 4. An evaporator 6 generates a gaseous mixture by heating a raw material and water using the combustion gas in a first evaporating part 6a, and unevaporated water is evaporated at a partition wall 11 which covers a second evaporating part 6b arranged at the lower side continuously following the first evaporating part 6a. In a reformer 8, hydrogen-containing gas is generated by passing the gaseous mixture from the second evaporating part 6b through a reforming catalyst which is heated by the combustion gas. In a carbon monoxide removing part 10, the amount of carbon monoxide in the hydrogen containing gas generated by the reformer 8 is reduced and hydrogen is generated. Since the partition wall 11 has a partition wall welding part 11b adhered to the second evaporating part 6b and a partition wall sliding part 11c which is press-fitted to the second evaporating part 6b and carries out thermal expansion moving, the hydrogen generation apparatus can be operated stably in preventing the partition wall 11 from being broken as opposed to thermal expansion and contraction of the hydrogen generation apparatus. |
