HYDROGEN
STORAGE ALLOYS
Hydrogen storage alloys offer a more compact and safer way to store hydrogen compared to high-pressure or liquid hydrogen systems. They can absorb and release hydrogen safely at room temperature and normal pressure.
With years of experience in battery development, FDK uses its technology to offer a range of hydrogen storage alloys for different storage needs.
Our hydrogen storage alloys are easy to activate and can quickly release hydrogen. Additionally, they are not subject to the High Pressure Gas Safety Act when stored. *When the stored pressure is less than 1MPa.
AB5 type alloy
AB5-type alloy is known for being user-friendly, with features such as easy activation and fast reaction rates.
