The power-generation characteristics and the electrode overpotential of the solid oxide fuel cell (SOFC) using doped lanthanum gallate perovskite-type oxide as an electrolyte were measured at temperatures below that of the typical SOFC using yttria-stabilized zirconia (YSZ) as an electrolyte. The oxide ion conductivity of the electrolyte, La 0.8 Sr 0.2 Ga 0...
Powder particles of tungsten oxide (WO 3 ) were irradiated by an electron beam with an energy of 200 keV in a transmission electron microscope (TEM) atroom temperature. A number of nanocrystals were induced inside the single crystal particle as a result of irradiation damage. Electron energy loss spectroscopy (EELS) analysis revealed a decrease in the oxygen content in the particle which suggested...
