Hydrogen supply system and method for operating same

Abstract

[Problem] To provide a hydrogen generation system and a method for operating the same which enable a quick change in an amount of hydrogen gas to be supplied. [Solution] A hydrogen supply system (1) includes a vaporizer (3) for vaporizing a hydrogen carrier in liquid form; a dehydrogenation reactor (4) for generating hydrogen from the vaporized hydrogen carrier provided from the vaporizer through a dehydrogenation reaction; and a control device (30) for controlling a flow rate of the vaporized hydrogen carrier flowing through an outlet of the vaporizer. The control device may adjust an amount of heat for heating the hydrogen carrier to thereby regulate the flow rate of the vaporized hydrogen carrier flowing through the outlet of the vaporizer. The hydrogen supply system (1) further comprises: a main passage (L6) connected to an outlet of the dehydrogenation reactor and passing through a first vaporizer; a bypass passage (L7) connected to the main passage and bypassing the first vaporizer; and a first flow control valve (V6) provided in at least one of the main passage and the bypass passage.
