This Small Business Innovation Research (SBIR) Phase I project focuses on the development of an innovative diffusion barrier for the preparation of Pd thin film on tubular porous stainless steel substrate. A thin Pd film supported on tubular porous SS substrate provides a commercially viable avenue for the use of palladium membranes for hydrogen production/recovery, particularly for large-scale applications. A micro-engineered diffusion barrier is proposed, which is able conceptually to accommodate the physical change of metal substrate surface, thermal mismatch, and other factors. More importantly this diffusion barrier offers flexibility in tailoring its pore size and surface topography to be optimal for the formation of an ultra-thin, defect free, and strongly adhered Pd film via electroless plating. The proposed diffusion barrier could offer a practically viable Pd-based hydrogen separation device, which can benefit fuel cell and industrial hydrogen applications, and greenhouse gas reduction.

这个小型企业创新研究(SBIR)第一阶段项目专注于开发一种创新的扩散屏障，用于在管状多孔不锈钢衬底上制备Pd薄膜。支撑在管状多孔SS衬底上的薄层Pd膜为使用钯膜生产/回收氢气提供了一条商业可行的途径，特别是在大规模应用中。提出了一种微工程扩散势垒，它在概念上能够适应金属衬底表面的物理变化、热失配等因素。更重要的是，这种扩散阻挡层可灵活调整其孔径和表面形貌，以便通过化学镀形成超薄、无缺陷且附着力强的Pd膜。提出的扩散阻挡层可以提供一种实际可行的Pd基氢分离装置，这将有利于燃料电池和工业氢的应用，并减少温室气体排放。
