Abstract
In hydrogen refueling stations, polymer O-rings are used for high-pressure hydrogen containers and transfer pipes to prevent gas leakage. A technology has been developed to measure the hydrogen uptake and diffusivity of the polymer materials used in these O-rings. The process involves charging the polymer material with hydrogen under a..... More
