1. A method of fabricating a hydrogen-selective membrane, comprising:
applying a metal leaf to a substrate;
annealing the metal leaf on the substrate to give an annealed metal leaf on the substrate;
applying a hydrogen-permeable metal to the annealed metal leaf on the substrate; and
annealing the hydrogen-permeable metal and the annealed metal leaf to give an alloy of the hydrogen-permeable metal and the metal leaf, wherein the hydrogen-selective membrane comprises the alloy disposed on the substrate.
