  Abstract

O-ring was used for gas sealing under the environment of high pressure hydrogen for valve and pipeline in hydrogen station and hydrogen storge vessel. The effect on high pressure hydrogen gas of 70 MPa in chemical structure and polymer matrix chain of studied O-ring have been observed by means of magic angle spinning nuclear magnetic resonance of 1H, 13C, 19F nuclei and electron spin resonance of radical ion. We have tried to understand the phenomena of deterioration/fracture mechanism caused by penetration/diffusion of hydrogen gas by employing these techniques.
