Hydrogen Storage Systems Lab
Machine-translated · View original
A lab that studies the loss of strength in metallic materials in hydrogen environments.
AboutAbout the lab
Clarifying how hydrogen affects metals
The Hydrogen Storage Systems Lab studies how the strength and ductility of metallic materials used in hydrogen equipment decrease in hydrogen gas.
When hydrogen enters the interior of a metal, a phenomenon called hydrogen embrittlement occurs, lowering strength and ductility. It is an obstacle to the safe design and cost reduction of hydrogen equipment.
The lab works on clarifying the mechanism of hydrogen embrittlement, establishing criteria for selecting metallic materials for use in hydrogen gas, and establishing strength design methods for hydrogen equipment.
On the lab's website, the lab is introduced under the name "Hydrogen Storage Systems Lab (Matsunaga Lab)."
Key terms
- Hydrogen embrittlement
- A phenomenon in which hydrogen enters the interior of a metal and lowers its strength and ductility
- Ductility
- The property of a metal that allows it to deform and stretch without breaking

ResearchResearch themes
In equipment that uses hydrogen, various metal components are exposed to hydrogen gas environments. The Hydrogen Storage Systems Lab investigates the mechanism of hydrogen embrittlement in metallic materials, aiming to contribute to building safer, lower-cost hydrogen storage, transport, and supply systems.
