The objectives of this project are to explore and develop novel protonic conductors for eventual use as H2 separation membranes.

Work is in progress to explore the development of materials with a layered crystallographic structure (i.e., pyrochlore-perovskite, cubic-perovskite and others), novel materials such as bismuth aluminates, and composites composed of alkaline earth carbonates/metal oxide composites.

A database of materials properties will be developed that will include thermal properties, mechanical properties, electrical properties, flux, and stability data in the environment of choice over a broad range of temperatures.

Additional flux testing will be performed on thin asymmetric membranes, prepared from materials with adequate properties for the desired environment.
