1. A hydrogen permeation membrane comprising: a niobium alloy with 5-25 wt. % of at least one element from the group consisting of ruthenium, rhenium, and rhodium. 2. A hydrogen permeation membrane according to claim 1, and further comprising at least one of zirconium and hafnium. 3. A hydrogen permeation membrane according to claim 1, wherein the alloy has 0.5-3.0 wt. % of zirconium. 4. A process for producing a hydrogen permeation membrane, comprising the steps of:applying at least one coating of at least one element from the group consisting of palladium, ruthenium, rhenium, platinum, gold, rhodium, zirconium, and hafnium on a substrate of one of niobium and a niobium alloy with at least one element from the group consisting of palladium, ruthenium, rhenium, platinum, gold, and rhodium to form a composite; andsubjecting the composite to a diffusion heat treatment. 5. A process according to claim 4, including applying the coating one of by the PVD process, by chemical deposition, by electrodeposition, and by mechanical plating. 6. A fuel cell comprising a hydrogen permeation membrane consisting of niobium alloy with 5-25 wt. % of at least one element from the group consisting of palladium, ruthenium, rhenium, platinum, gold, and rhodium. 7. A fuel cell having a hydrogen permeation membrane produced by:applying at least one coating of at least one element from the group consisting of palladium, ruthenium, rhenium, platinum, gold, rhodium, zirconium, and hafnium on a substrate of one of niobium and a niobium alloy with at least one element from the group consisting of palladium, ruthenium, rhenium, platinum, gold, and rhodium to form a composite; andsubjecting the composite to a diffusion heat treatment.
