PROBLEM TO BE SOLVED: To provide a fuel supply unit that can reduce air stream sound occurring due to jetting of fuel gas with a simple construction.SOLUTION: A hydrogen supply unit 24 having at least one injector 48 for adjusting the flow rate and pressure of hydrogen gas, and a lead-out passage 68 through which hydrogen gas jetted from the injector 48 is led out, has a nozzle hole 70 which is formed to be branched from the lead-out passage 68 and associated with each injector 48, and a diffusion member 56 for diffusing the hydrogen gas. The hydrogen gas jetted from the injector 48 is led out to the lead-out passage 68 through the nozzle hole 70, and the diffusion member 56 is disposed in the lead-out passage 68 and formed to confront the exit portions 80 of all the nozzle holes 70.SELECTED DRAWING: Figure 2 |
