It will automatically open when the weight exceeds 1kg/c1.
A valve that automatically closes when the pressure drops below 0 kg/crA is preferable, and such safety valves that automatically open and close in response to pressure are already commercially available. For example, when MmNi4.681o,4 is used as the metal hydride alloy, P is 10 kg/cn! The temperature reached is 55℃

This is to prevent the particles from scattering from the container and contaminating hydrogen-using equipment, since the hydrogen particles become quite fine. Note that a similar filter 15 is usually attached to the opening of a container filled with hydrogen, thereby doubly preventing metal hydride from scattering. Similarly, a pressure gauge 1 is connected to the conduit on the second connector 9 side.
6 is attached to monitor the amount of hydrogen stored in the metal hydride container during use. Furthermore, since the hydrogen release reaction from the metal hydride is an endothermic reaction, a heater (not shown) can be attached to the pedestal if necessary.
