摘要： An in-vehicle liquid hydrogen tank includes: an inner tank that stores liquid hydrogen; an outer tank that accommodates the inner tank; and a heat-insulation material that is arranged in a heat-insulation clearance as a clearance between the inner tank and the outer tank and holds the inner tank to be separated from an inner surface of the outer tank. The heat-insulation clearance has: a vacuum area that is not filled with the heat-insulation material; and an area that is filled with the heat-insulation material and thus allows the inner tank to be surface-supported by the heat-insulation material.

摘要： A liquid hydrogen storage system includes: a hydrogen tank that stores liquid hydrogen; a first channel that communicates between the hydrogen tank and outside of a vehicle; a reaction section that causes hydrogen gas flowing through the first channel to react with oxygen for conversion into water and discharges water to the outside of the vehicle through the first channel; and a first safety valve that is provided between the hydrogen tank and the reaction section, and is opened at the time when an internal tank pressure as an internal pressure of the hydrogen tank exceeds a first open reference value, so as to discharge the hydrogen gas in the hydrogen tank to the reaction section.
