| 摘要 |
According to the present invention, a high-pressure hydrogen container that is filled with hydrogen at high pressures, in which at least one elastomer is used as a sealing material, such elastomer having a hydrogen gas permeability coefficient or helium gas permeability coefficient of 5.0x10-10 to 5.0x10-9 cm3 (STP).cm/cm2.sec.cmHg, is provided. The following main technical objectives for realizing sealing with an elastomer material for a high-pressure hydrogen container (CHG tank) system for fuel-cell vehicles are achieved: (1) good durability in variable pressure environments of high-pressure hydrogen is imparted to such elastomer material; and (2) good anti-permanent deformation properties in low-temperature and high-temperature environments are imparted to such elastomer material.
