PROBLEM TO BE SOLVED: To provide a high pressure hydrogen production apparatus where, even when the thicknesses of a solid high polymer electrolytic membrane and an anode power feeder are reduced by hydrogen pressure, there occurs no gas between the solid high polymer electrolytic membrane and the cathode power feeder. SOLUTION: The high pressure hydrogen production apparatus is equipped with power feeders 3, 4 provided on both the sides of a solid high polymer electrolytic membrane 2, separators 5, 6, and fluid passages 10, 12. The respective power feeders 3, 4 are energized, and water fed to the fluid passage 12 in the separator 6 is electrolyzed, thus high pressure gaseous hydrogen is obtained at the fluid passage 10 in the separator 5. The separator 5 is equipped with a first chamber 7, a second chamber 8 having a cross-sectional area larger than that of the first chamber 7, a shielding member 9 airtightly shielding both the chambers 7, 8, movably provided freely forwards and backwards along the inner wall of both the chambers 7, 8 and provided with the fluid passage 10, and a communication passage 11 bypassing the shielding member 9 and enabling both the chambers 7, 8 to communicate with each other. The shielding member 9 is made forward in the direction of the power feeder 3 by the pressure of hydrogen fed to the second chamber 8 via the communication path 11, and the power feeder 3 is pressed against the solid high polymer electrolytic membrane 2. The power feeders 3, 4 are composed of a porous sintered compact made of titanium. COPYRIGHT: (C)2006,JPO&NCIPI
