The proposed research is to develop thin Pd-based composite membranes for hydrogen separation applications at high temperatures. The short term objectives of this research are to: (1) seek Pd-based alloys possessing both appropriate hydrogen permeability and good thermal stability, (2) develop techniques for depositing promising alloys on suitable substrates to form thin pinhole-free Pd-based composite membrane, and (3) study impacts of impurities on hydrogen permeation performance of these thin alloy composite membranes. The long term objectives are to: (1) develop thin Pd-based alloy composite membranes with appropriate stability at high temperatures (500-650C) and (2) scale-up the techniques for preparing these composite membranes so that they have sufficient area to be suitable for practical industrial applications.
