摘要： PROBLEM TO BE SOLVED: To stably decrease CO in reformed gas in a hydrogen production apparatus to be used for a fuel cell.
SOLUTION: A section where the reformed gas passing through a cooler 21 enters is provided with a narrowing part 23 where the cross-sectional area of the passage for the reformed gas is narrowed. The amount of water supplied to the cooler 21 is controlled based on the temperature of the narrowing part 23. Even when the temperature of the reformed gas is inhomogeneously distributed in the cross-sectional direction of the flow, the gas is narrowed and blended in the narrowing part, thus the average temperature of the reformed gas can be detected. By controlling the water amount of the cooler 21 based on the average gas temperature, the catalyst temperature can be controlled as a whole to the active temperature, and CO in the reformed gas can be stably decreased.
