NOVELTY - The high-pressure hydrogen manufacturing apparatus (1) has solid polymer electrolyte film (2), cathode power supply material (3) and anode power supply material (4) which are provided at both sides of film (2), separator (5,6), and fluid path (10,12) provided at each separator, to which materials (3,4) is exposed. Separator (5) has chamber (7) which accommodates material (3), reverse side chamber (8), and interruption component (9).    USE - For manufacturing high-pressure hydrogen.    ADVANTAGE - The apparatus efficiently enables manufacture of high-pressure hydrogen. Generation of gap on solid-polymer electrolyte film and cathode power-supply material is prevented, even if thickness of solid-polymer electrolyte film and anode power-supply material reduces by hydrogen pressure.    DETAILED DESCRIPTION - The high-pressure hydrogen manufacturing apparatus (1) has a solid polymer electrolyte film (2), a cathode power supply material (3) and an anode power supply material (4) which are mutually opposed and provided at the both sides of the film (2), a separator (5,6) laminated by each power supply material, and a fluid path (10,12) provided at each separator, to which materials (3,4) is exposed. Apparatus (1) electrolyzes water supplied to the fluid path of anode side separator by supplying electricity to each material (3,4). While supplying water to the fluid path of anode side separator, high-pressure hydrogen gas is obtained in fluid path of cathode side separator. The cathode side separator has a chamber (7) which accommodates the cathode power supply material, a reverse side chamber (8) which has cross-section greater than chamber (7) in direction parallel to the cathode power supply material, and is connected to chamber (7) at reverse side of cathode power supply material, an interruption component (9) which interrupts chambers (7,8) airtightly and is equipped with fluid path, such that the component move forwards or backwards freely in direction of the cathode power supply material along inner wall of chambers, and a communication path (11) which bypasses interruption component and connects chambers (7,8). The interruption component is made to move forward in power supply material direction with pressure of hydrogen which is generated by electrolysis in the fluid path, and is supplied to chamber (8) via the communicating path from the chamber (7). The power supply material is pressed on the solid polymer electrolyte film.
