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.

这项小型企业创新研究（SBIR）I阶段项目着重于开发用于在管状多孔不锈钢基材上制备PD薄膜的创新扩散屏障。在管状多孔SS底物上支撑的薄PD膜为使用钯膜的商业可行途径提供了氢生产/回收的途径，尤其是用于大规模应用。提出了一个微型工程扩散屏障，可以从概念上适应金属底物表面，热不匹配和其他因素的物理变化。更重要的是，这种扩散屏障在调整孔径和表面地形方面具有灵活性，以最佳地形成超薄，无缺陷的无缺陷，并且通过电镀层强烈粘附的PD膜。拟议的扩散屏障可以提供实际上可行的基于PD的氢分离装置，该设备可以使燃料电池和工业氢的应用以及减少温室气体造成。
