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.
