Compared to conventional technology, palladium membranes offer an increased flow of high-purity hydrogen from a gaseous stream. The membranes are prepared by electroless- deposition plating of Pd (or Pd alloy) on a porous support. The process results in a unique hexagonal structure. High flux translates to smaller separators or lower cost for the same purity of hydrogen.
Low-cost, high-flux separation membranes can be deployed in multiple applications for hydrogen production, hydrogen separation, and hydrogen purification. Hydrogen purifiers, for example, are used in light-emitting diode production, and next-generation turbines use hydrogen for clean fuel production. A hydrogen separator can also feed stationary fuel cells or deliver the gas as a transportation fuel.
