We report on the intermediate-temperature synthesis (973 K) and operation (<750 K) of Ce4.67(SiO4)3O-based thin-film oxy-apatites. The apatite thin films show the high conductivity of ∼0.05–0.5 S/cm and excellent stability in reducing atmosphere (<10−17 atm), which makes promising these materials as anodes for intermediate-temperature solid oxide fuel cell (SOFC) application. The proto-type SOF...

In this study, a samarium cerium electrolyte-supported solid oxide fuel cell (SOFC) was assembled with Ce0.8Sm0.2O2−δ (SDC) electrolyte, La0.58Sr0.4Fe0.8Co0.2O3-δ (LSCF) as cathode and WNi-Ce as anode. A porous layer of SDC between anode and electrolyte was used to improve adhesion of the anode ink. The cell performance was investigated with hydrogen and three simulated biogas mixtures (CH4/CO2...

Final Report: Theoretical Design and Experimental Evaluation of Molten Carbonate Modified LSM Cathode for Low Temperature Solid Oxide Fuel Cells Report Title Using DFT and experimental methods, the following topics have been deeply explored. (1) Interaction between oxygen and molten carbonate; (2) Fabrication and test of SOFCs with MC modified LSM cathodes; (3) Low-temperature SOFCs using MC mo...

The number of blastomeres of human day 3 embryos is one of the most important criteria for evaluating embryo viability. However, due to the transparency and overlap of blastomeres, it is a challenge to recognize blastomeres automatically using a single embryo image. This study proposes an approach based on least square curve fitting (LSCF) for automatic blastomere recognition from a single imag...

Pd-, Cu-, Ni- and NiCu-BaZr₀.₁Ce₀.₇Y₀.₁Yb₀.₁O₃₋δ anodes, designated as M-BZCYYb, were prepared by impregnating M-containing solution into BZCYYb scaffold, and investigated in the aspects of electrocatalytic activity for the reactions of H₂ and CH₄ oxidation and the resistance to carbon deposition. Impregnation of Pd, Ni or NiCu significantly reduced both the ohmic (RΩ) and polarization (RP) los...
