PROBLEM TO BE SOLVED: To enable miniaturization and structural simplification for a unit which is integrally provided with an injector and first and second pressure sensors.SOLUTION: A hydrogen supply unit 12 has an introducing block 41 containing an introducing passage 41a for hydrogen gas, a lead-out block 42 containing a lead-out passage 42a for hydrogen gas, injectors 14 to 16 for adjusting the flow rate and pressure of hydrogen gas, a secondary pressure sensor 32 for detecting hydrogen gas pressure in the introduction passage 41a, and a tertiary pressure sensor 33 for detecting hydrogen gas pressure in the lead-out passage 42a. The entrance side of each of the injectors 14 to 16 is connected to the introduction passage 41a, and the exit side of each of the injectors 14 to 16 is connected to the lead-out passage 42a. The hydrogen gas introduced into the introduction passage 41a is jetted to the lead-out passage 42a by each of the injectors 14 to 16, thereby reducing the pressure of the hydrogen gas. The respective injectors 14 to 16, the secondary pressure sensor 32 and the tertiary pressure sensor 33 are arranged to be sandwiched by the introduction block 41 and the lead-out block 42. |
