    摘要： This liquid hydrogen storage tank includes a tank body, a dike, a pump, and a housing chamber. The tank body includes an inner tank that forms a storage space for storing liquid hydrogen therein, and an outer tank that is formed by interposing a thermal insulation layer between the outer tank and the inner tank. The dike includes an outer peripheral surface and an inner peripheral surface that is in contact with the side plate of the outer tank. The dike is formed upwardly so as to surround the outer periphery of the tank body. The pump discharges liquid hydrogen inside the inner tank through the side plate of the inner tank to the outside. The housing chamber is disposed between the outer peripheral surface of the dike and the storage space, and houses the pump.

    摘要： A double-shell tank that stores a low temperature liquid includes: an inner shell having a non-spherical hollow shell shape and including therein a storing portion; an outer shell that covers the inner shell; and powdered thermal insulation that is filled in a space surrounded by an outer wall of the inner shell and an inner wall of the outer shell to become a heat insulating layer. Then, a size of a top portion gap between the inner shell in an empty state and the outer shell is larger than a size of a bottom portion gap between the inner shell and the outer shell. A thickness of the powdered thermal insulation of the top portion gap in the empty state is larger than the size of the bottom portion gap.
