Document Type and Number:
WIPO Patent Application WO/2021/085434
Kind Code:
A1
Abstract:
[Problem] To provide a hydrogen gas supply system with which it is possible to supply hydrogen gas continuously for a long period of time. [Solution] A hydrogen gas supply system 10 comprises a hydrogen gas generation device 11 that electrolyzes pure water and generates hydrogen gas (oxygen gas), and a hydrogen-absorbing-alloy compressed gas cylinder (canister) 12 that is filled with a hydrogen-absorbing alloy. The hydrogen gas generated by the hydrogen gas generation device 11 is supplied to a gas supply line 7 (including a supercharger 2) via a main line (piping) 13. A sub-line 14 that supplies the hydrogen gas inside the hydrogen-absorbing-alloy compressed gas cylinder 12 to the main line 13 is connected to the main line 13, and pressure adjustment valves 15, 16 are provided to the main line 13 and the sub-line 14. A signal pertaining to the speed of the engine is sent to a control device 17 from a governor 3, and a signal that corresponds to the valve opening for supplying an additional amount of hydrogen in accordance with the load state of the engine is sent from the control device 17 to the pressure adjustment valves 15, 16.
