| Research Abstract |
The fifth transition metals have known to have high hydrogen permeability and are usually coated with thin Pd to prevent the surface oxidation. The utilization of the metals with Pd at high temperatures more than 500 C, however, leads to the degradation due to the reaction between the metals and Pd. We found that the insertion of WO3 between the meals and the Pd layer and the new system can be used for the hydrogen permeation at temperatures higher than 500 C.
