SEALING MATERIAL FOR HIGH-PRESSURE HYDROGEN VESSEL, AND HIGH-PRESSURE HYDROGEN VESSEL

摘要

PPROBLEM TO BE SOLVED: To solve big technical subjects of (1) excellent durability in a pressure fluctuating environment of high pressure hydrogen and (2) excellent settling resistance in a low- to high-temperature environment, for attaining a seal by an elastomer material for a high-pressure hydrogen vessel (CHG tank) system for a fuel cell car. PSOLUTION: This sealing material for the high-pressure hydrogen vessel is mainly composed of a silicone rubber consisting of dimethylsiloxane segment, methylvinylsiloxane segment and diphenylsiloxane segment, and the high-pressure hydrogen vessel uses the sealing material.
