As known, the palladium alloy having the property that is permeable to hydrogen.
The hydrogen separation membrane module developed this time results from unique application of the company's proprietary metal-filter forming technology to the property of the palladium alloy.
A palladium alloy thin film is wound around a cylindrical body of which the outside diameter is 34 mm and the length is 300 mm.
Leakage problem of hydrogen gas was perfectly solved. The company's proprietary film bonding technology was used for this purpose. As a result, an extremely high impurity hydrogen could be generated.
A unique three-layer structure was employed for the palladium alloy thin film formed. With use of the three-layer structure, the film strength and film durability were increased, ensuring long service life and high reliability. It is noted that those advantageous features have not been attained in those fields.

The hydrogen separation membrane module may be reduced in size, light in weight and low in cost. The palladium alloy membrane module is made entirely of metal. A desired number of the membrane modules may be combined coupled together by welding in accordance with a desired amount of generated hydrogen gas. The membrane modules may be combined so as to satisfy a large amount of hydrogen generated in large-scale hydrogen production plants. |
