摘要：Flowerlike CeO₂ coated with Sr₂Fe_1.5Mo_0.5O_x (Sr-Fe-Mo-oxide) nanoparticles exhibits enhanced conductivity at low temperatures (300–600 ^oC), e.g. 0.12 S cm⁻¹ at 600 ^oC, this is comparable to pure ceria (0.1 S cm⁻¹ at 800 ^oC). 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 ^oC. The mechanism of enhanced conductivity and cell performance were analyzed. These results provide a promising strategy for developing advanced low-temperature SOFCs.
