PROBLEM TO BE SOLVED: To efficiently obtain targeted product hydrogen by assuredly removing, based on a simple constitution and steps, water included within high-pressure hydrogen generated from a high-pressure water electrolysis apparatus and to economically constitute a dew point measurement apparatus.SOLUTION: The water electrolysis system 10 comprises a high-pressure water electrolysis apparatus 12 for generating hydrogen by electrolyzing water, a first dehumidifying apparatus 16 for removing water within the hydrogen discharged from the high-pressure water electrolysis apparatus 12, and a back pressure valve 20 configured on the downstream side of the first dehumidifying apparatus 16 for sustaining the hydrogen at a specified goal pressure. A branched pipeline 46 is configured between the first dehumidifying apparatus 16 and back pressure valve 20, whereas a decompression valve 50, a dew point meter 52, and an ON/OFF valve 54 are configured on the branched pipeline 46. |
