Abstract: Abstract Oxide anodes composed of 60 wt% Gd0.1Ce0.8Ni0.1O2 (GDCN)- 40 wt% (Sr0.9La0.1)0.9Ti0.9Ni0.1O3 (SLTN) composites were prepared and tested on (ZrO2)0.89(Sc2O3)0.1(CeO2)0.01 (SSZ) electrolyte-supported SOFC cells utilizing a (La0.75Sr0.25)0.98MnO3 (LSM)-SSZ cathode, in 3%-humidified hydrogen fuel at 800 °C. Improved electrochemical… read more here.

Abstract: Abstract Fluorite-doped Gd0.1Ce0.9O1.95 (GDC) polycrystalline electrolytes (Gd0.1Ce0.9-xCaxF2xO1.95-2x, x = 0.00–0.10) have been synthesized for the first time, which have the same concentration of oxygen vacancies as GDC but show extraordinarily enhanced oxide ionic conductivities, along with suppressed… read more here.
