Abstract: Provided is a hydrogen supply system that supplies hydrogen. The hydrogen supply system includes: a dehydrogenation reaction unit that subjects a raw material including a hydride to a dehydrogenation reaction to obtain a hydrogen-containing gas; a circulation system that circulates a reaction inactive fluid to the dehydrogenation reaction unit; and a control unit that controls the hydrogen supply system. The control unit circulates the reaction inactive fluid with the circulation system in a case where production of the hydrogen-containing gas in the dehydrogenation reaction unit is stopped.
