Summary:To prevent a hydrogen electrode containing metal components from being damaged, without increasing its operation cost upon generating hydrogen.SOLUTION: There is provided a hydrogen generation system 100 comprising an electrolysis module 19 supplying a hydrogen electrode 11 containing metal components with steam to generate hydrogen by steam electrolysis, a hydrogen storage facility 40 storing hydrogen being generated, a steam supplier 20 supplying the hydrogen electrode 11 with steam, an adjuster 50 adjusting the supply rate of hydrogen supplied from the hydrogen storage facility 40 to the hydrogen electrode 11 and the supply rate of steam supplied from the steam supplier 20 to the hydrogen electrode 11, and a controller 80 that controls the adjuster 50 so that a heating medium supply state of supplying a heating medium from a heating medium supplier 70 to the hydrogen electrode 11 is switched to a steam supply state of supplying steam from the steam supplier 20 to the hydrogen electrode 11 upon starting the electrolysis module 19, in response to the temperature of the electrolysis module 19 exceeding a first switching temperature.SELECTED DRAWING: Figure 1 【課題】水素を生成する際の運用コストを増大させることなく、金属成分を含む水素極が損傷することを防止する。【解決手段】金属成分を含む水素極１１に水蒸気を供給して水蒸気電解により水素を生成する電解モジュール１９と、生成された水素を貯蔵する水素貯蔵設備４０と、水素極１１に水蒸気を供給する水蒸気供給部２０と、水素貯蔵設備４０から水素極１１に供給される水素の供給量と、水蒸気供給部２０から水素極１１に供給される水蒸気の供給量と、を調整する調整部５０と、電解モジュール１９を起動する際に、電解モジュール１９が第１切替温度を上回ったことに応じて、加熱媒体供給部７０から水素極１１に加熱媒体が供給される加熱媒体供給状態を、水蒸気供給部２０から水素極１１に水蒸気が供給される水蒸気供給状態に切り替えるよう調整部５０を制御する制御装置８０と、を備える水素生成システム１００を提供する。【選択図】図１
