With their characteristic high permeability, and the ability to produce pure hydrogen at temperatures up to 500 °C, Pd-based membranes are presently the state-of-the-art in hydrogen-selective alloy membranes (Paglieri and Way 2002, Uemiya 2004). However, given the high cost of Pd (around $US 180 per square metre per micrometre thickness), current research is aimed at reducing the amount of palladium required, either through depositing thin films on porous supports, or through the development of non-Pd alloy membranes.
