This Small Business Innovation Research Phase II 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. During Phase II the diffusion barrier will be developed to a commercial scale membrane unit for performing field tests. Pd membranes due to their excellent hydrogen permeability and selectivity can streamline existing hydrogen separation and purification processes dramatically for fuel cell and hydrogen separation applications. The projected worldwide market size when fully matured is in the range of $1 billion/yr. Refineries' demand for hydrogen is expected to post annual growth in excess of 10% as refiners use more hydrogen to meet clean fuel regulations. A Pd-base hydrogen selective membrane suitable for large scale operations will play a major role in meeting this demand, particularly for the retrofit market, such as hydrogen recovery from waste refinery streams, as an add-on stage for existing steam reformer for incremental capacity, etc. In summary 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阶段II项目的重点是开发用于在管状多孔不锈钢基材上制备PD薄膜的创新扩散障碍。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。 在II期期间，扩散屏障将开发到商业尺度膜单元进行现场测试。 PD膜由于其出色的氢渗透性和选择性而引起的，可以极大地简化现有的氢分离和纯化过程，以供燃料电池和氢分离应用。预计的全球市场规模完全成熟，范围为10亿美元/年。由于炼油厂使用更多的氢来满足清洁燃料法规，预计炼油厂对氢的需求预计将超过10％。适用于大规模操作的PD碱氢选择性膜将在满足这一需求中发挥重要作用，尤其是对于改造市场，例如从废物精炼厂流中恢复氢，作为现有蒸汽改革仪的增量能力的附加阶段等。总结起来，拟议的扩散屏障可以使基于PD的基于PD的氢分离式的燃料和工业式的造型，并使其受益于PD基于PD的氢气。
