Thermochemical Materials

Solar Thermo-Chemical Hydrogen (STCH) materials

This research focuses on discovery of new redox materials and optimization of the high-potential STCH candidates by high-throughput experimental methods, for chemical generation of hydrogen at elevated temperature. Such studies not only provide an efficient way to uncover new STCH materials, but also help to better understand fundamental links between chemical composition, crystal structure, and STCH performance.

Solid Oxide Electrolysis Cell (SOEC) materials

The purpose of this research is to develop materials for intermediate temperature proton-conducting solid oxide electrolysis cell (H-SOEC) that can electrochemically generate hydrogen at elevated temperatures. The high-throughput screening methods involve combinatorial thin film deposition and spatially-resolved characterization of the resulting materials. Studies also include evaluation of electrochemical performance (E-XPS) and grain boundary diffusion (TOF-SIMS).
