High pressure hydrogen gas is known to adversely affect metallic components of compressors, valves, hoses, and actuators. However, relatively little is known about the effects of high pressure hydrogen on the polymer sealing and barrier materials also found within these components. More study is required in order to determine the compatibility of common polymer materials found in the components of the hydrogen fuel delivery infrastructure with high pressure hydrogen.

- High pressure hydrogen significantly impacts the friction and wear of polymers, which is crucial for applications in hydrogen vehicle refueling stations like seals and valves.
- Although much is known about hydrogen's adverse effects on metals, understanding its effects on polymers is still limited and warrants further investigation.
- Initial studies, including in situ tests using a custom tribometer, show that polymers like nitrile butadiene rubber experience increased friction and wear in high pressure hydrogen compared to argon and air.
