The invention discloses a hydrogen storage container and a hydrogen-powered vehicle. The hydrogen storage container comprises an inner container, an outer container, a high-pressure gas layer and a pressure difference control valve, wherein the high-pressure gas layer and the pressure difference control valve are arranged between the inner container and the outer container. An inner cavity of the inner container is used for storing hydrogen, and the pressure difference control valve enables the pressure of the hydrogen in the inner container to be smaller than or equal to that of the high-pressure gas layer all the time. According to the hydrogen storage container, the air pressure borne by the outer peripheral face of the hydrogen storage inner container is always larger than the hydrogen pressure borne by the inner wall face, the air pressure difference between the inner wall face and the outer wall face of the hydrogen storage inner container is reduced, and the phenomenon of hydrogen embrittlement caused by hydrogen adsorption of metal materials in the state of high hydrogen pressure difference is avoided; the diffusion rate of hydrogen atoms in metal lattices can be reduced, the possibility of local hydrogen gathering and bubble generation is reduced, the occurrence probability of the hydrogen embrittlement phenomenon is reduced, the safety of the hydrogen storage container is improved, and then the safety performance of the hydrogen power vehicle is improved.

    本发明公开了一种储氢容器及氢动力车辆,该储氢容器包括内胆、外胆、设置于内胆与外胆之间的高压气体层及压差控制阀。内胆的内腔用于储存氢气,压差控制阀可以使内胆内的氢气气压始终小于或等于高压气体层的气压。本发明专利提供的储氢容器使得储氢内胆的外周面受到的气压始终大于内壁面受到的氢气气压,降低了储氢内胆内外壁面的气压差,避免金属材料处于高氢气气压差的状态下吸附氢气发生氢脆的现象,即能够减缓氢原子在金属晶格中的扩散速率,降低局部氢气聚集和产生气泡的可能性,降低氢脆现象的发生概率,提高储氢容器的安全性,进而提高氢动力车辆的安全性能。
