Development of Palladium-Alloy Membranes for Hydrogen Separation and Purification

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...

Microfabrication of Palladium–Silver Alloy Membranes for Hydrogen Separation

In this paper, a process for the microfabrication of a wafer-scale palladium—silver alloy membrane (Pd–Ag) is presented. Pd–Ag alloy films containing 23 wt% Ag were prepared by co-sputtering from pure Pd and Ag targets. The films were deposited on the unetched side of a 110 -oriented silicon wafer in which deep grooves were etched in a concentrated KOH solution, leaving silicon membranes with a...

Strain-gradient-induced Effects in Palladium Alloy Membranes

There has been increasing appreciation over recent years of the importance of the studies reported by Gorsky in the 1930s concerning the influences of strain gradients on the processes of diffusion in metals (1-3). These strain gradients can, for example, be produced by mechanical bending. As a particular case of strain induced diffusion, evidence has been obtained from anelastic effects-such a...

Micromachined Palladium - Silver Alloy Membranes for Hydrogen Separation

This paper presents wafer-scale palladium silver alloy membranes, fabricated with a sequence of wellknown thin film and silicon micromachining techniques. The membranes have been tested in a gas permeation system to determine the hydrogen permeability and hydrogen selectivity. Typical flow rates of 1 mol H2 /m.s have been measured with a minimal selectivity of 1500 for H2/He. The membranes have...
