To suppress condensation of oxygen on a surface of an outer tank, in a liquefied hydrogen tank that does not have a vacuum insulating structure between the outer tank and an inner tank.SOLUTION: A liquefied hydrogen tank comprises an inner tank storing liquefied hydrogen, an outer tank surrounding the inner tank, an outer shell surrounding the outer tank, a first heat insulating layer arranged in a first region between the inner tank and the outer tank, and a second insulating layer arranged in a second region between the outer tank and the outer shell. The first region is substantially atmospheric pressure or low vacuum filled with first gas that is hydrogen gas or helium gas, and the second region is filled with second gas containing at least one of inert gas and dry air. With the liquefied hydrogen stored in the inner tank, a temperature of the outer tank is a predetermined outer tank control temperature that is higher than a condensation point of oxygen and equal to or lower than the atmospheric temperature.SELECTED DRAWING: Figure 3

    【課題】内槽と外槽の層間に真空断熱構造を有しない液化水素タンクにおいて、外槽の表面における酸素の凝縮を抑制する。【解決手段】液化水素タンクは、液化水素が収容される内槽と、内槽を包囲する外槽と、外槽を包囲する外殻と、内槽と外槽の間の第1領域に配置された第1断熱層と、外槽と外殻との間の第2領域に配置された第2断熱層とを備える。第1領域は水素ガス又はヘリウムガスである第1ガスが充填された実質的に大気圧又は低真空であり、第2領域は不活性ガス及び乾燥空気の少なくとも一方を含む第2ガスが充填されており、内槽に液化水素が収容された状態で、外槽の温度が酸素の凝縮点より高く且つ大気温度以下の所定の外槽管理温度である。【選択図】図3
