FASE Technologies Functional energy related materials CO 2 -free fossil energy ◦ Gas separation membranes ◦ Fuel cells Hydrogen technology ◦ Fuel cells ◦ Steam electrolysis ◦ Photo-electrochemical splitting of water High temperature corrosion Sensors for extreme conditions ◦ High temperature, corrosive environments, Space, Nuclear power, Energy processes Clean water and air – photocatalysis Thermoelectric materials ◦ Solar and waste heat utilisation

FASE Science Defects in crystals ◦ Defect chemistry ◦ Transport ◦ Emphasis on oxides and hydrogen Solid state reactions Electrode reactions Relation between structure, composition, and functional properties Design, make, characterize, and model new materials Questions: ◦ H + in oxides? H in oxides? H - in oxides? ◦ N 3- in oxides? ◦ Cation diffusion in oxides? Lifetime of devices? ◦ Novel solid-state proton conductors? ◦ Charge transfer mechanisms in electrodes? ◦ Why do grain boundaries behave so differently? ◦ How does a photocatalyst work?

6 FASE Methods Synthesis Sample preparation Structure: XRD Microstructure: SEM Measurements of concentration and transport of defects –Thermogravimetry –Reaction rates –Diffusion –Permeability –Electrical properties Electrochemical studies –Fuel cell tests –Electrode kinetics –Photoelectrochemistry Further characterization, often in collaboration: –TEM, XPS, SIMS, ND… Computational simulations of structure and defects

Examples of current FASE project possibilities Pulsed Laser Deposited (PLD) films for fuel cells, electrolysers, and gas separation membranes Proton conducting oxides for fuel cells and electrolysers; measurements and computational approaches Electrodes for H + -conducting fuel cells and electroysers New proton-electron mixed conductors for gas separation membranes Water splitting or CO 2 -to-fuel generation by solid-state photoelectrochemistry Pure water by photocatalysis – is it possible? Thermoelectric oxides – from heat to electricity Grain boundaries and interfaces; TEM and properties Diffusion and surface kinetics – use of isotopes and ToF-SIMS Nitrogen defects in oxides Combined computational and experimental studies and more; depends on what is hot when you start, and your interests…
