PROBLEM TO BE SOLVED: To provide a water storage tank capable of storing reform water supplied to a reformer in a state where a small content of air bubbles is contained.SOLUTION: A plate member 511 of a water storage tank 5 exists in a storage space 530 and extends toward the inner surface of a wall part 501 forming the storage space 530, from at least a lower position of a water inflow port 513 to the diagonally downward in the vertical direction D2. Between the lower end of the plate member 511 and the inner surface of the wall part 501, a water inner surface circulation passage 531 is formed which can circulate water W3 and which supplies water W3 flowing along the plate member 511 to the inner surface of the wall part 501 from the plate member 511 so as to flow along the inner surface the wall part 501.SELECTED DRAWING: Figure 3 |
