Flowerlike CeO(2) microspheres coated with Sr(2)Fe(1.5)Mo(0.5)O(x) nanoparticles for an advanced fuel cell

Flowerlike CeO(2) coated with Sr(2)Fe(1.5)Mo(0.5)O(x) (Sr-Fe-Mo-oxide) nanoparticles exhibits enhanced conductivity at low temperatures (300–600 (o)C), e.g. 0.12 S cm(−1) at 600 (o)C, this is comparable to pure ceria (0.1 S cm(−1) at 800 (o)C). Advanced single layer fuel cell was constructed using t...

description Flowerlike CeO(2) coated with Sr(2)Fe(1.5)Mo(0.5)O(x) (Sr-Fe-Mo-oxide) nanoparticles exhibits enhanced conductivity at low temperatures (300–600 (o)C), e.g. 0.12 S cm(−1) at 600 (o)C, this is comparable to pure ceria (0.1 S cm(−1) at 800 (o)C). Advanced single layer fuel cell was constructed using the flowerlike CeO(2)/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 (o)C. The mechanism of enhanced conductivity and cell performance were analyzed. These results provide a promising strategy for developing advanced low-temperature SOFCs.
