Fuel cell electric vehicles require efficient and safe hydrogen storage technology. The volumetric method was used to determine the storage capacity of hydrogen on homemade carbon nanomaterials (carbon nanotubes and carbon nanofibers) at room temperature. The results show that hydrogen has the largest adsorption capacity on carbon nanomaterials when the equilibrium pressure is between 9 MPa and 10 MPa at 25 ℃, and the mass ratio of H to C is 3.1%. This phenomenon is explained correspondingly, and the principle of storing hydrogen in carbon nanomaterials is preliminarily discussed. This will help to further improve the storage capacity of hydrogen in carbon nanomaterials in order to facilitate the ultimate realization of carbon nanomaterial hydrogen storage technology in engineering applications
