    • PROBLEM TO BE SOLVED: To provide a method for stopping a hydrogen production apparatus and a fuel cell system in a safe, economical and easy manner while suppressing catalyst degradation without incorporating a nitrogen gas cylinder, a purge gas mechanism or an automatic opening and closing valve corresponding to negative pressure.
      SOLUTION: The method for stopping the hydrogen production apparatus equipped with a reformer, a shift reactor and a selective oxidation reactor or the method for stopping the fuel cell system comprising the hydrogen production apparatus and a fuel cell includes: a step of purging a passage containing a reforming catalyst, a shift reaction catalyst and a selective oxidation catalyst with steam; a step of cutting off the passage from the outside world; and an air introduction step where, in order to restore the internal negative pressure of the passage, when the temperature of the shift catalyst becomes ≤40°C, air is introduced into the passage from a downstream side of the shift catalyst.
