The liquefied hydrogen tank is provided with: an inner tank for accommodating liquefied hydrogen; an outer tank surrounding the inner tank; a housing surrounding the outer tank; a first insulating layer disposed in a first region between the inner tank and the outer tank; and a second heat insulating layer disposed in a second region between the outer tank and the housing. The first region is filled with a first gas that is hydrogen or helium and is substantially atmospheric pressure or low vacuum, and the second region is filled with a second gas that includes at least one of an inert gas and dry air, and in a state in which liquefied hydrogen is housed in the inner tank, the first gas is substantially atmospheric pressure or low vacuum. The temperature of the outer tank is a predetermined outer tank management temperature that is higher than the condensation point of oxygen and that is equal to or lower than the atmospheric temperature.

    液化氢罐具有:内槽,其收纳液化氢;外槽,其包围内槽;外壳,其包围外槽;第一隔热层,其配置于内槽与外槽之间的第一区域;以及第二隔热层,其配置于外槽与外壳之间的第二区域。第一区域填充有作为氢气或氦气的第一气体,实质上为大气压或低真空,第二区域填充有包含惰性气体和干燥空气中的至少一方的第二气体,在内槽中收纳有液化氢的状态下,外槽的温度为比氧的冷凝点高且为大气温度以下的规定的外槽管理温度。
