Solid-state hydrogen storage device

An apparatus comprising:

• a solid-state hydrogen storage container configured to store solid-state hydrogen supplied from a hydrogen supply source;
• a fuel cell stack configured to receive hydrogen from the solid-state hydrogen storage container to generate electric power;
• a hydrogen line configured to connect the hydrogen supply source to the fuel cell stack via the solid-state hydrogen storage container, wherein the hydrogen line is connected to an inlet of the solid-state hydrogen storage container and an outlet of the solid-state hydrogen storage container such that the hydrogen passes via the solid-state hydrogen storage container to enable storage or discharge of the hydrogen;
• and
• a cooling water line configured to be connected between a cooling water supply source and the fuel cell stack, wherein the cooling water line is connected to the inlet of the solid-state hydrogen storage container and the outlet of the solid-state hydrogen storage container to supply or discharge cooling water to or from the solid-state hydrogen storage container.
