To provide a high-pressure hydrogen manufacturing device capable of obtaining excellent electrolytic efficiency while no space is generated between a solid polymer electrolyte film and a cathode power supply body by the pressure of gaseous hydrogen generated on a cathode side.
The high-pressure hydrogen manufacturing device comprises a solid polymer electrolyte film 2, at least one single cell 7 comprising a cathode power supply body 3, an anode power supply body 4, a cathode separator 5 and an anode separator 6, and fixing means 14, 15, 16 to fix the solid polymer electrolyte film 2, the power supply bodies 3, 4 and the separators 5, 6 from both sides of the single cell 7. High-pressure gaseous hydrogen is generated on the cathode side by conducting the power supply bodies 3, 4 and performing electrolysis of water to be fed to the anode side. The fixing means 14, 15, 16 are capable of withstanding the pressure stress higher than the pressure of gaseous hydrogen obtained in the single cell 7. Preferably, the fixing means 14, 15, 16 are capable of withstanding the pressure stress higher than the pressure of gaseous hydrogen in a range of 1-40 MPa.
