This SBIR Phase I program involves the development of a solid-state proton conductor (SSPC) suitable for intermediate temperature applications, i.e., 100 to ~300C. We will develop an ultra-thin (1 m) dense film (using a properly selected inorganic electrolyte), which is supported on our existing commercial ceramic membranes as a solid-state proton conductor (SSPC). Based upon the specific conductivity, the proposed ultra-thin proton conductor can potentially deliver a hydrogen permeance comparable to or better than existing polymeric (e.g., Nafion) and high temperature (e.g., perovskite) proton conductors and permit operation at the intermediate temperature ranges. This SSPC can be used as (i) a hydrogen pump for hydrogen recovery from waste/recycle streams, (ii) a 2nd stage hydrogen separator to conventional pressure-driven membranes for further hydrogen separations without an interstage compressor, and (iii) a membrane reactor (MR) to enhance the conversion/yield of industrial dehydrogenation reactions.

SBIR第一阶段计划涉及固态质子导体（SSPC）的开发，适用于中间温度应用，即100至~300℃。我们将开发一种超薄（1米）的致密膜（使用适当选择的无机电解质），它作为固态质子导体（SSPC）支撑在我们现有的商用陶瓷膜上。基于特定的导电性，所提出的超薄质子导体可以潜在地提供与现有聚合物（例如，Nafion）和高温（例如，钙钛矿）质子导体相当或更好的氢导电性，并允许在中间温度范围内操作。该SSPC可以用作(i)从废物/循环流中回收氢气的氢泵，（ii）用于常规压力驱动膜的第二级氢分离器，用于进一步的氢分离，而无需级间压缩机，以及（iii）膜反应器（MR），以提高工业脱氢反应的转化率/产量。
