1. A palladium-gold alloy coated vanadium or vanadium alloy-based gas separation membrane, comprising a palladium-gold alloy coating on a vanadium or vanadium alloy-based gas separation membrane, the coating having a thickness of between 100 nm and 5 microns and having a composition of from Pd60Au40 to Pd95Au5,
wherein the palladium-gold alloy coating has a bulbous and/or cauliflower shaped morphology having a lightness of less than 50, where a lightness of 100 represents the lightest of whites and a lightness of 0 represents the darkest of blacks, measured using a Chroma Meter; and
wherein the palladium-gold alloy coated vanadium or vanadium alloy-based gas separation membrane has a hydrogen permeability of at least 1×10−7 mol/m/s/Pa0.5 at temperatures between 325 to 350° C.
