SBIR Phase I: A Solid State Proton Conductor as a Hydrogen Pump

该SBIR第一阶段计划涉及适用于中温应用的固态质子导体（SSPC）的开发，即，100 ~ 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），这是支持我们现有的商业陶瓷膜作为固态质子导体（SSPC）。基于比电导率，所提出的超薄质子导体可以潜在地递送与现有聚合物（例如，Nafion）和高温（例如，钙钛矿）质子导体并允许在中间温度范围内操作。 该SSPC可用作（i）用于从废物/再循环流中回收氢气的氢气泵，（ii）第二级氢气分离器，用于常规压力驱动膜的进一步氢气分离，而无需级间压缩机，和（iii）膜反应器（MR），以提高工业脱氢反应的转化率/产率。

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.
