Abstract
Describe the hydrogen permeation properties of
Pd-Cu alloy membranes at high pressures.
Researchers prepared a 7 μm thick Pd-Cu alloy membrane on an
alumina-modified porous nickel support (PNS) using their developed magnetron
sputtering and Cu-reflow method.
They mounted the membrane in a stainless steel
permeation cell with a gold-plated stainless steel O-ring. Helium leak testing
confirmed that the membrane and membrane module were free of defects.
Permeation tests were then conducted using hydrogen at various temperatures.
