Determination of permeation properties of hydrogen gas in sealing rubbers using thermal desorption analysis gas chromatography

Abstract Permeation properties of hydrogen gas (H2) into nitrile butadiene rubber (NBR), ethylene propylene diene monomer (EPDM), and fluoroelastomer (FKM) which are the strong candidates for sealing material in H2 energy infrastructures, was quantified using a thermal desorption analysis gas chroma...
