A hydrogen production system includes: a steam generator heating supplied raw water and generating steam; an electrolytic cell receiving the steam and generating hydrogen and oxygen through a high temperature electrolysis; a cooling unit cooling an unreacted part of the steam in the high temperature electrolysis and changing the unreacted part of the steam into steam condensate; a gas/liquid separator performing gas/liquid separation on the generated hydrogen and the generated steam condensate; a hydrogen compression unit compressing the separated hydrogen and transmitting thermal energy generated when the hydrogen is compressed, to the raw water; and a hydrogen storage unit storing the compressed hydrogen.

Hydrogen production system and method for producing hydrogen

A high-pressure treatment apparatus comprises a first solid reservoir, a second solid reservoir connected to the first solid reservoir through a first connecting pipe, a high-pressure reactor connected to the second solid reservoir through a second connecting pipe, means for feeding reaction medium into the high-pressure reactor, a first sealing unit and a second sealing unit intervened respectively in the first connecting pipe and second connecting pipe, a first fluid feed unit for feeding a first fluid between the first sealing unit and the second sealing unit, a second fluid feed unit for feeding a second fluid between the second sealing unit and the high-pressure reactor, and means for opening the second sealing unit at the time of shut-off of the first sealing unit and controlling the first fluid and the second fluid to form a pressure-gradient so that pressure between the first sealing unit and the second sealing unit and pressure between the second sealing unit and the high-pressure reactor decrease gradually toward the high-pressure reactor.
