ABO3-δ (A = La, Sr, B Fe, Co) perovskites are useful in a wide range of applications, including their recent exploration for application high-temperature optical oxygen sensing energy conversion devices such as solid oxide fuel cells. To elucidate the dependence functional properties and vacancy formation on defect chemistry composition, first principles calculations presented. The obtained results show that (VO) energies order LaFeO3 > LaCoO3 SrFeO3 SrCoO3. Furthermore, influence VO...
Due to the time required test fuel cell degradation experimentally, a physics-based model which can predict be valuable tool. Grain coarsening and resulting microstructure evolution is primary mode of degradation. In this study, multi-physics presented performance loss as function caused by in electrodes an LSM-YSZ/YSZ/Ni-YSZ SOFC. Microstructural properties are updated from their initial values using functional relations derived experimental data. Specie charge transport equations solved...
The use of carbon dioxide as a feedstock for broad range products can help mitigate the effects climate change through long‐term removal or part circular economy. Research on capture and conversion technologies has intensified in recent years, interest deploying these is growing fast. However, sound understanding environmental economic impacts required to drive fast deployment avoid unintended consequences. Life cycle assessments (LCAs) techno‐economic (TEAs) are useful tools quantify...
The demand for real-time sensors in harsh environments at elevated temperature is significant and increasing. In this manuscript, the chemical sensing using optical response through practical fiber platform demonstrated, principle component analysis coupled with targeted experimental film characterization to understand fundamental layer properties, which dominate measured gas responses complex mixtures. More specifically, tin-doped indium oxide-decorated fabricated sol–gel method show stable...
The steam is commonly supplied with H2 to the anodes of Ni-based solid oxide fuel cells (SOFCs). Humidified also widely used for emerging perovskite SOFCs, although influences H2O on hydrogen oxidation reaction (HOR) their surfaces have not been well understood yet. In this work, effects HOR Sr2Fe1.5Mo0.5O6−δ (SF1.5M), La0.5Sr1.5Fe1.5Mo0.5O6−δ (LSFM), and Pr0.5Sr1.5Fe1.5Mo0.5O6−δ (PSFM) were systematically investigated using electrochemical impedance spectroscopy (EIS) electrical...
The U.S. Department of Energy (DOE)-National Technology Laboratory (NETL) in Morgantown, WV has developed the hybrid performance (HyPer) project which a solid oxide fuel cell (SOFC) one-dimensional (1D), real-time operating model is coupled to gas turbine hardware system by utilizing hardware-in-the-loop simulation. To assess long-term stability SOFC part system, electrochemical degradation due conditions such as current density and utilization have been incorporated into successfully...
