This Small Business Innovation Research (SBIR) Phase I project will develop and evaluate a new class of mixed proton and electron conducting materials which are capable of operating at intermediate temperatures (400-700C). These materials could be used as membranes in a wide variety of hydrogen separation applications resulting in an efficient, economic, and selective process. The composite materials of interest will be based on a proton conducting oxyacid salt and a metallic or ceramic electronically conducting component. Composite powders of different components and compositions will be fabricated using various preparation techniques. These will then be fabricated into dense membrane disks, which will subsequently be tested for their structural, electrical, and transport properties with the proton and electronic conductivity being of particular interest. The composite materials showing the most promise will then be incorporated into laboratory scale membrane separation configurations and evaluated for their ability to mediate hydrogen. The development of a new membrane-based hydrogen separation process will have multiple applications for use in industry. It would allow for the separation and purification of hydrogen in one step. Furthermore, these membrane systems could act as novel reactors for carrying out different chemistries such as hydrogenation and dehydrogenation reactions at potentially lower costs and higher yields.

这个小企业创新研究（SBIR）第一阶段项目将开发和评估一种新型的混合质子和电子导电材料，这种材料能够在中间温度（400-700摄氏度）下工作。这些材料可以作为膜广泛用于各种氢分离应用，从而产生高效，经济和选择性的过程。感兴趣的复合材料将基于质子导电氧酸盐和金属或陶瓷电子导电元件。不同成分和组成的复合粉末将使用各种制备技术制备。然后将其制作成致密的膜盘，随后将对其结构，电学和传输特性进行测试，其中质子和电子导电性是特别感兴趣的。最有希望的复合材料将被纳入实验室规模的膜分离配置，并评估其调解氢的能力。一种新的膜基氢分离工艺的开发将在工业上有多种应用。它可以一步分离和净化氢。此外，这些膜系统可以作为新型反应器，以更低的成本和更高的收率进行不同的化学反应，如加氢和脱氢反应。
