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 CO2-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
