Abstract

Ni-Cu/Gd-doped ceria composite anode powder was prepared via sol-gel route. The acid/alkoxide ratio (0.6-4) and water/alkoxide (>25) were found to be suitable for obtaining homogenous gel with an increasing chance of gel formation as the amount of water increases. XRD results of the powder fired at 900℃ showed the (Ce, Gd)O_2, (Cu, Ni)O, NiO and CuO phases.
