Hydrogen purifier

Hydrogen purifier

A hydrogen purifier is a device to purify hydrogen, the ultra-high purified hydrogen is needed for applications like PEM fuel cells . Different methods are used but the most promising technique for removing unwanted contaminants uses dense thin-metal membrane purifiers which are compact, relatively inexpensive and simple to use [ [http://www.hydrogen.bham.ac.uk/h2purify.htm Hydrogen purification membranes] ] .

Palladium membrane hydrogen purifiers

The palladium membrane is typically a metallic tube of a palladium and silver alloy material possessing the unique property of allowing only monatomic hydrogen to pass through its crystal lattice when it is heated above 300°C.

Pressure swing adsorption

Pressure swing adsorption is used for the removal of carbon dioxide (CO2) as the final step in the large-scale commercial synthesis of hydrogen
