To provide a fuel supply system capable of re-liquefying hydrogen gas generated by pressure reduction of surplus liquefied hydrogen of critical pressure or higher so as to be sucked into a pump.SOLUTION: A fuel supply system 1A includes a tank 2 for storing liquefied hydrogen, and a fuel supply line 3 for leading out the liquefied hydrogen from the tank 2. A first pump 4A, a stirring device 5, and a second pump 4B are provided in the fuel supply line 3. The second pump 4B increases a pressure of the liquefied hydrogen to a critical pressure or higher. The fuel supply system 1A includes a reflux line 7 which is branched off from the fuel supply line 3 in a downstream side of the second pump 4B, is connected to the stirring device 5, and is provided with a pressure reduction valve 71. The stirring device 5 stirs hydrogen gas generated by pressure reduction by the pressure reduction valve 71 together with the liquefied hydrogen flowing through the fuel supply line 3 so as to condense the hydrogen gas.SELECTED DRAWING: Figure 1

    【課題】余剰の臨界圧力以上の液化水素の減圧によって生じた水素ガスを再液化してポンプに吸入させることができる燃料供給システムを提供する。【解決手段】一実施形態に係る燃料供給システム1Aは、液化水素を貯留するタンク2と、タンク2から液化水素を導出する燃料供給ライン3を含む。燃料供給ライン3には、第1ポンプ4A、撹拌装置5および第2ポンプ4Bが設けられている。第2ポンプ4Bは、前記液化水素を昇圧して臨界圧力以上とする。また、燃料供給システム1Aは、第2ポンプ4Bの下流側で燃料供給ライン3から分岐して撹拌装置5につながる、減圧弁71が設けられた還流ライン7を含む。撹拌装置5は、減圧弁71による減圧によって生じた水素ガスを燃料供給ライン3を流れる液化水素と撹拌することで前記水素ガスを凝縮する。【選択図】図1
