Palladium Membrane for Hydrogen Purification
Tanaka Precious Metals has succeeded in developing an ultra-thin membrane for an ultra-high purification process of hydrogen gas.
Palladium is the only metal that has hydrogen permselectivity. Tanaka Precious Metals has succeeded in developing a thin Pd alloy membrane which can be used in the purification process of hydrogen and exploits this permselectivity of Pd to hydrogen. With our ultra-thin film processing technology and high purification technology, we are able to offer highly reliable hydrogen permeable films with very few pinholes and maximum hydrogen permeability. Our hydrogen permeable films are available as cut to size foils or cut foils, also as rolled foil or tube materials.
- High-purity hydrogen gas purifiers
- Steam reforming based hydrogen production units, etc.
