System filled with hydrogen absorbing alloy

A system filled with hydrogen absorbing alloy in which a hydrogen supply side tank containing a hydrogen absorbing alloy and a hydrogen absorption side tank containing a hydrogen absorbing alloy are connected to each other via a hydrogen transfer pathway, and hydrogen is transferred from the hydrogen supply side tank to the hydrogen absorption side tank, the system filled with hydrogen absorbing alloy comprising:

• a heating device that heats the hydrogen supply side tank;
• and
• a cooling device that cools the hydrogen absorption side tank,
• wherein a configuration in which at least one of a heating load by the heating device and a cooling load by the cooling device can be controlled such that the heating load and the cooling load are in a predetermined ratio.
