    Abstract: A hydrogen system includes: a compressor that includes an anode, a cathode, and an electrolyte membrane interposed therebetween and generates compressed hydrogen by applying a voltage between the anode and the cathode to move protons extracted from anode fluid supplied to the anode to the cathode; a voltage applicator that applies the voltage between the anode and the cathode; a first flow passage through which a cathode off-gas containing the compressed hydrogen discharged from the cathode is supplied to the anode of the compressor; a first on-off valve disposed in the first flow passage; and a controller that causes the voltage applicator to apply the voltage with the first on-off valve opened during a period of time from startup of the hydrogen system until supply of the cathode off-gas to a hydrogen reservoir is started.

    Abstract: Provided is a hydrogen supply system that supplies hydrogen. The hydrogen supply system includes: a dehydrogenation reaction unit that subjects a raw material including a hydride to a dehydrogenation reaction to obtain a hydrogen-containing gas; a heating mechanism that heats the dehydrogenation reaction unit by using electric power; and an electric power supply unit that supplies at least one of electric power based on renewable energy and electric power based on thermal power generation equipped with carbon dioxide capture and storage to the heating mechanism.

    Abstract: Provided is a hydrogen supply system that supplies hydrogen. The hydrogen supply system includes: a dehydrogenation reaction unit that subjects a raw material including a hydride to a dehydrogenation reaction to obtain a hydrogen-containing gas; a hydrogen purification unit that removes a dehydrogenation product from the hydrogen-containing gas obtained in the dehydrogenation reaction unit to obtain a purified gas including high-purity hydrogen; and a degassing unit that removes an inorganic gas contained in the raw material on an upstream side of the dehydrogenation reaction unit in a flow of the raw material.

    Abstract: Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Erzeugung von Wasserstoff, wobei ein erster Ammoniak enthaltender Einsatzstoff (3, 3') einem über einen importierten Energieträger (13) beheizten ersten Spaltreaktor (R1) zugeführt wird, um Ammoniak mit katalytischer Unterstützung in Wasserstoff und Stickstoff zu spalten und ein heißes, Wasserstoff und Stickstoff enthaltendes ersten Spaltgas (6, 6') zu erhalten. Kennzeichnend hierbei ist, dass ein zweiter Ammoniak enthaltender Einsatzstoff (4, 2) in einem zweiten Spaltreaktor (R2) zu einem Wasserstoff und Stickstoff enthaltenden zweiten Spaltgas (7, 3') umgesetzt wird, wobei das heiße erste Spaltgas (6, 6') zur Beheizung des zweiten Spaltreaktors (R2) eingesetzt und dabei abgekühlt wird.

    Abstract: A hydrogen production apparatus of the present disclosure includes: a gas supply unit that supplies a first hydrogen-containing gas containing hydrogen; a first electrochemical device having a first anode side inlet to make the first hydrogen-containing gas flow in and a first cathode side outlet to make a second hydrogen-containing gas having a higher concentration of hydrogen than the first hydrogen-containing gas flow out; and a second electrochemical device having a second anode side inlet to make the second hydrogen-containing gas flow in and a second cathode side outlet to make a third hydrogen-containing gas having a higher concentration of hydrogen than the second hydrogen-containing gas flow out. It is configured such that the ratio of the pressure value of the third hydrogen-containing gas at the second cathode side outlet to the pressure value of the second hydrogen-containing gas at the second anode side inlet is higher than the ratio of the pressure value of the second hydrogen-containing gas at the first cathode side outlet to the pressure value of the first hydrogen-containing gas at the first anode side inlet.
