Title: Method of making sulfur-resistant composite metal membranes
Usefulness: Method of making sulfur-resistant composite metal membranes
Summary: For fabricating sulfur-resistant composite metal membrane i.e. sulfur-resistant composite palladium-gold alloy membrane (claimed) useful in purification of hydrogen that produces energy in fuel cell power systems.
Novelty: Fabricating sulfur-resistant composite metal membrane used to purify hydrogen involves seeding substrate with palladium crystallite; decomposing organic ligand; reducing crystallite to metallic form; and annealing palladium and gold films
