Abstract
The amount of high-temperature steam supplied from external equipment is reduced. Provided is a hydrogen production system () including a reactor () that allows a humidified process fluid output from a humidifier () to react in the presence of a catalyst to transform carbon monoxide in the process fluid into carbon dioxide; a second channel (B) through which the high-temperature process fluid that has reacted in the reactor () flows; a circulation channel (C) through which excess water in the humidifier () is circulated; and a first heat exchanger (), disposed at an intersection of the circulation channel (C) and the second channel (B), for heat exchange between the high-temperature process fluid that has reacted in the reactor () and the fluid circulated through the circulation channel (C).
