Flowerlike CeO2 coated with Sr(2)Fe(1.5)Mo(0.5)Ox (Sr-Fe-Mo-oxide) nanoparticles exhibits enhanced conductivity at low temperatures (300-600 degrees C), e.g. 0.12 S cm(-1) at 600 degrees C, this is comparable to pure ceria (0.1 S cm(-1) at 800 degrees C). Advanced single layer fuel cell was constructed using the flowerlike CeO2/Sr-Fe-Mo-oxide layer attached to a Ni-foam layer coated with the conducting transition metal oxide. Such fuel cell has yielded a peak power density of 802 mWcm(-2) at 550 degrees C. The mechanism of enhanced conductivity and cell performance were analyzed. These results provide a promising strategy for developing advanced low-temperature SOFCs.
