The invention relates to a
solid hydrogen source device for
hydrogen fuel, and belongs to the technical field of
hydrogen storage devices. Safety, portability and environmental adaptability of a solidhydrogen source to hydrogen utilization are achieved. According to the solution, a tank opening is formed in a
hydrogen storage tank, a valve is mounted at the tank opening, a sealing ring is mountedbetween the valve and the tank opening, a heat exchange pipeline is of a double-spiral structure and is fixedly arranged on the inner wall of the
hydrogen storage tank in a coiling manner, and a heatmass transfer inlet and a
heat mass transfer outlet of the heat exchange pipeline respectively penetrate through the valve and extend to the outside of the
hydrogen storage tank; a cavity is formed in the axis position in a tank body of the hydrogen
storage tank, a hydrogen charging / discharging pipeline penetrates through the valve and communicates with the cavity, a plurality of material bins are arranged on the periphery of the cavity, the size of each material bin is not smaller than 4 / 5 of that of an inner cavity of the tank body of the hydrogen
storage tank, a diaphragm is arranged on aside wall of each material bin, and the material bins are filled with
solid hydrogen storage
alloy powder. The device is simple in structure, safe, efficient, portable and suitable for various environments and has good reproducibility and stability.
