1. A method for separating hydrogen from a hydrogen-containing fluid, comprising:
separating a hydrogen-containing fluid stream at a temperature from about 573 to about 1,173 degrees Kelvin into a permeate stream comprising substantially molecular hydrogen and a retenate stream substantially depleted of molecular hydrogen compared to the hydrogen-containing fluid stream by permeating hydrogen through a palladium-alloyed membrane having a nitrogen leakage growth rate at about 823 degrees Kelvin of no more than about 7×10−12 (mol/m2/s/Pa)/h, and wherein the palladium-alloyed membrane comprises palladium and one or more of ruthenium, rhodium, iridium, platinum, silver, gold and osmium.
