Abstract
Provided is a tank equipped with a container body to store hydrogen gas, a self-closing valve provided in the container body and configured to start and stop discharging the hydrogen gas by opening and closing, a fusible plug provided in the container body and configured to open when a predetermined temperature is reached to release the gas in the tank, and a member that delays heat transfer to the self-closing valve later than to the container body and/or a member that promotes heat transfer to the fusible plug when the hydrogen cartridge is heated.
