Process for producing high-pressure hydrogen and system for producing high-pressure hydrogen

A system for producing high-pressure hydrogen, comprising:

• a hydrogen generator into which water and a hydrogen-generating material which reacts with water to generate hydrogen are introduced, said hydrogen-generating material and said water being weighed so that hydrogen having a target high pressure is produced;
• a hydrogen-storing vessel for storing a high-pressure hydrogen generated by said hydrogen generator;
• and a connecting member adapted to connect said hydrogen generator and said hydrogen-storing vessel to each other in a course of filling said hydrogen-storing vessel with the high-pressure hydrogen and adapted to disconnect said hydrogen generator and said hydrogen-storing vessel from each other after said hydrogen-storing vessel is filled with the high-pressure hydrogen.
