RE: Membrane for H2 seperation
A metal membrane (Pt/Pd) separates great, but is not cost effective at much more than bench scale. A polymer membrane might work, but have a more limited temperature range and the "small amount of other gases" might be a show stopper if the other gas is say methylene chloride or HCl. This also becomes a cost issue, as the systems have a minimum size to be worth the manufacturers cost
