No fatal leak of hydrogen gas occurred on the O-ring seal made of the Fluoroelastomer during the endurance cycle test that simulates the hydrogen filling process of fuel cell vehicle(FCV). However, wear damages and extrusion of O-ring seal were observed after the durability test including the cycle of high compression and decompression of hydrogen pressure at high temperature, indi-cating that developed elastomer still does not have sufficient durability under realistic severe environment.
