| Abstract: |
| This article reviews the research progress on the sealing performance of rubber sealing rings under high-pressure hydrogen，with a focus on the influencing factors of the hydrogen permeability performance in rubber and sealing failure of rubber sealing ring under high-pressure hydrogen，and the analysis method of the sealing performance of rubber sealing ring under high-pressure hydrogen.The influence factors of the hydrogen permeability performance in rubber are summarized as filler type，hydrogen pressure and rubber type.The influence factors of the sealing failure of rubber sealing ring under high-pressure hydrogen are mainly explosion relife effect and volume expansion，the analysis methods of the sealing performance of rubber sealing ring under high-pressure hydrogen mainly include in-situ visual analysis and finite element analysis.And the future research directions of rubber sealing rings for high-pressure hydrogen are to extend the types of fillers and rubber，and development systematic research and test equipment. |
