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.

这个小企业创新研究第二阶段项目的重点是开发一种创新的扩散屏障，用于在管状多孔不锈钢基底上制备Pd薄膜。支撑在管状多孔SS基底上的薄Pd膜为钯膜用于氢气生产/回收，特别是用于大规模应用提供了商业上可行的途径。 在第二阶段，扩散屏障将发展成商业规模的膜装置，用于进行现场试验。Pd膜由于其优异的氢渗透性和选择性，可以显著简化现有的氢分离和纯化过程，用于燃料电池和氢分离应用。预计完全成熟后的全球市场规模为10亿美元/年。炼油厂对氢气的需求预计将以每年10%以上的速度增长，因为炼油厂使用更多的氢气来满足清洁燃料法规。适用于大规模操作的Pd基氢选择性膜将在满足这种需求方面发挥主要作用，特别是对于改造市场，例如从废炼油厂流中回收氢，作为现有蒸汽重整器的附加阶段以增加容量等。总之，所提出的扩散屏障可以提供实际可行的Pd基氢分离装置，这可以有益于燃料电池和工业氢应用以及温室气体减少。
