Hydrogen Permeable Films
TANAKA has succeeded in developing an ultra-high purification process for hydrogen gas.
Palladium is the only metal that has hydrogen permselectivity. TANAKA has succeeded in developing a purification process for hydrogen gas that exploits this permselectivity. With our ultra-thin film processing technology and highpurification technology, we are able to offer highly reliable hydrogen permeable films with maximum hydrogen permeability.
Applications
High-purity hydrogen gas purifiers, steam reforming based hydrogen production units, etc.
