Abstract:
1. A gas tank, comprising: a tank main body filled with a gas; a heat-insulating layer provided on an external surface of the tank main body; a pressure-reduction device which is provided at one end of the tank main body, and which reduces a pressure in the tank main body by releasing the gas from the tank main body; a transferring component which extends from the pressure-reduction device toward the other end of the tank main body, and which transfers heat and pressure; and a meltable member provided in the pressure-reduction device, wherein the member melts when a temperature becomes equal to or greater than a predetermined temperature in order to cause the pressure-reduction device to release the gas from the tank main body, wherein the transferring component includes a thermally expandable substance filled in the transferring component, and a pressure increasing together with a thermal expansion of the substance is transferred to the pressure-reduction device, and wherein the substance thermally expands together with a phase-change when heated, and the pressure-reduction device obtains a thrust force for releasing the gas from the tank main body based on an increased pressure in the transferring component.
