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. <br/><br/>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.
