PROBLEM TO BE SOLVED: To rapidly pressurize the inside of a liquid hydrogen tank without using a liquid hydrogen pump in a hydrogen fuel supply system that supplies liquid hydrogen stored in the tank as hydrogen gas to a point of use.SOLUTION: A hydrogen fuel supply system 1 comprises: a tank 2 that stores liquid hydrogen; a supply line 4 that extracts and vaporizes the liquid hydrogen in the tank 2, and supplies it to a point of use 3; and a pressurization line 5 that compresses and pressurizes hydrogen gas produced by vaporizing the liquid hydrogen in the tank 2 with a compressor 59, and sends the pressurized hydrogen gas to a gas phase part in the tank 2.SELECTED DRAWING: Figure 1 【課題】タンクに貯蔵されている液体水素を水素ガスとしてユースポイントへ供給する水素燃料供給システムにおいて、液体水素ポンプを使わずに液体水素タンク内を速やかに昇圧する。【解決手段】水素燃料供給システム１は、液化水素を貯えたタンク２と、タンク２内の液化水素を取り出して気化し、ユースポイント３へ供給する供給ライン４と、タンク２内の液化水素が気化された水素ガスを圧縮機５９で圧縮して昇圧し、昇圧された水素ガスをタンク２内の気相部へ送る加圧ライン５とを備える。【選択図】図１
