HYDROGEN GENERATION SYSTEM AND HOT WATER PRODUCTION SYSTEM

摘要

Disclosed is a hydrogen generation system (2A) which comprises: a hydrogen generation unit (201) in which a first liquid that contains water is held, and a part of the water contained in the first liquid is decomposed into hydrogen and oxygen and at least a part of the first liquid is heated by being irradiated with sunlight; a first heat exchanger (207) for cooling the first liquid and heating a second liquid by heat exchange between the first liquid, which has been heated in the hydrogen generation unit (201), and the second liquid; and a mechanism (for example, a circulation line (204) and a pump (205)) for introducing the first liquid, which has been cooled in the first heat exchanger (207), into the hydrogen generation unit (201).
