Abstract

Hierarchically-ordered NiO-Ce_0.8Gd_0.2O_1.9 (GDC) composite anode powders were synthesized using eggshell membranes as biotemplates. The morphology of the as-synthesized powders depended on the kind of Ni precursor and the use of EDTA as a chelating agent. Hierarchically-ordered anode powders were obtained from Ni chloride and Ni acetate precursors with EDTA. The Ni-GDC anode synthesized from Ni chloride precursor with EDTA exhibited the lowest polarization resistance at 800 C and an activation energy of 0.01 Ω cm² and 0.74 eV, respectively, in humidified H ₂. In accordance with the polarization resistance results, the 0.5-mm thick GDC electrolyte-supported single cell with the Ni-GDC anode synthesized from Ni chloride precursor with EDTA showed a maximum power density of 0.34 W cm^-2 at 800 C with humidified H₂ fuel.
