SOLID-STATE HYDROGEN STORAGE DEVICE

An apparatus may comprise 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 and an outlet of the solid-state hydrogen storage container to enable storage or discharge of the hydrogen, and a cooling water line connected between a cooling water supply source and the fuel cell stack, wherein the cooling water line is connected to the inlet and the outlet of the solid-state hydrogen storage container.
