摘要: Flowerlike CeO2 coated with Sr2Fe1.5Mo0.5Ox (Sr-Fe-Mo-oxide) nanoparticles exhibits enhanced conductivity at low temperatures (300–600 oC), e.g. 0.12 S cm−1 600 oC, this is comparable to pure ceria (0.1 S 800 oC). Advanced single layer fuel cell was constructed using the flowerlike CeO2/Sr-Fe-Mo-oxide attached a Ni-foam conducting transition metal oxide. Such has yielded peak power density of 802 mWcm−2 550 oC. The mechanism and performance were analyzed. These results provide promising strategy for developing advanced low-temperature SOFCs.
