High-Pressure Hydrogen Compatible Polymer Materials Lab
Machine-translated · View original
The lab investigates the mechanisms by which rubber and resin materials break down under high-pressure hydrogen.
AboutAbout the lab
Exploring how materials that seal hydrogen break down.
Prof. Nishimura's lab studies rubber and resin materials exposed to high-pressure hydrogen.
In the hydrogen equipment that makes up a hydrogen energy society, rubber and resin materials are used to seal hydrogen gas.
There is concern that hydrogen sealing materials such as O-rings may break down when exposed to high-pressure hydrogen gas, or when hydrogen gas is repeatedly pressurized and depressurized.
The lab is working to elucidate the phenomenon in which rubber and resin materials placed in high-pressure hydrogen are broken down by the hydrogen gas.
Key terms
- O-ring
- A ring-shaped rubber part that seals gaps to prevent gas and other substances from leaking
- thermal desorption spectroscopy
- An analytical method in which a sample is gradually heated and the gas released from it is examined
- nuclear magnetic resonance (NMR)
- A method that examines how atomic nuclei respond in a magnetic field in order to learn about the structure and motion of a substance
ResearchResearch themes
The lab aims to elucidate the phenomenon in which rubber and resin materials used to seal hydrogen equipment break down in high-pressure hydrogen gas. It examines how hydrogen dissolves into the materials and studies the relationship between this and how they break down.
