The invention belongs to the technical field of hydrogen storage, and particularly relates to a solid hydrogen storage tank. The tank comprises a tank body, hydrogen storage bed body elements, air guide pipes, a filter plate and a valve. The plurality of hydrogen storage bed elements are stacked inside the tank body, and each hydrogen storage bed element comprises a hydrogen storage material layer, a heat conducting layer and a flexible wrapping layer; longitudinal through holes are formed in the hydrogen storage bed body elements, and the air guiding pipes are placed in the through holes; andthe heat conducting layers and the flexible wrapping layers are made of a metal material so as to enhance heat transferring of a hydrogen storage bed and stabilize the bed. The solid hydrogen storagetank is simple in structure and easy to manufacture and machine, the adopted hydrogen storage bed body element structure can improve the heat transfer performance of the hydrogen storage bed and accelerate the hydrogen filling/discharging speed, meanwhile, hydrogen storage material powder is prevented from migrating, so that uniform distribution of the hydrogen storage material powder in the bedis ensured, stress concentration generated on the tank body due to hydrogen absorption expansion of the hydrogen storage material is avoided, and the service life and safety of the solid hydrogen storage tank are prolonged and improved.
