“…The activation energies were calculated to be 0.844 and 0.509 eV for the SBFT and SBFT–SDC anodes, respectively. The R p values of SBFT and SBFT–SDC are also lower than those of previously studied anodes, such as the composite anode SrMoO 3– YSZ (8.0 Ω cm 2 at 800°C under a H 2 atmosphere) and La 0.5 Sr 1.5 MnO 4+δ (8.7 Ω cm 2 at 800 °C under a 5% H 2 /Ar atmosphere) . The excellent electrochemical performance of the SBFT and SBFT–SDC anodes is closely related to the formation of metal nanoparticles that have high catalytic activity and oxygen vacancies.…”

Because of the excellent catalytic activity of nanoparticles, their in situ exsolution on perovskite surfaces has received extensive attention in the field of catalysis. Herein, a unique A- and B-site coexsolved double perovskite, SrBiFeTiO6−δ (SBFT), is used as an anode material in a solid oxide fuel cell (SOFC). A study of its crystal structure confirmed that the cubic structure of the SBFT perovskite has reasonable structural stability under a hydrogen (H2) atmosphere, even though metallic Bi and Fe exsolve from the perovskite lattice. Electrical conductivity results show that the exsolved nanoparticles improve the conductivity of the perovskite. X-ray photoelectron spectroscopy results indicate that the SBFT surface features Ti3+/4+, Fe3+/2+/0, Bi3+/0, and Sr2+ valence states. The output peak power densities of a single cell with SBFT–Ce0.8Sm0.2O1.9 as an anode are 280 and 503 mW cm–2 in ethanol and under a H2 atmosphere at 800 °C, respectively. In ethanol, at 800 °C, the fuel cell is relatively stable for over 30 h under a voltage of 0.5 V. All of the results show that the coexsolving of elements on a perovskite is a promising material design approach for creating SOFC anodes that have excellent properties.

“…The perovskite oxide ABO 3 has received considerable attention due to the excellent MIEC and stability and can be used as the electrode material in SOFCs. [6][7][8] Since the BO 6 octahedron ultimately determines the electronic properties of perovskites, B-site element substitution is a common approach to modify the electronic properties and catalytic activity by forming double perovskites, A 2 BB 0 O 6 . [9][10][11] One of the frequently used Bsite elements is Mo owing to its multivalent features, which provide the Mo-based perovskites with a high oxygen vacancy concentration and excellent catalytic capacity.…”

Solid oxide fuel cell (SOFC) anodes made by SrMoO3 substituting for Ni of SOFC. Porous SrMoO3 and YSZ (8mol%Y2O3-ZrO2) were synthesized with activated carbon hard template by liquid phase method, and nanoparticles Gd0.2Ce0.8O1.9 (GDC) impregnated porous SrMoO3-YSZ with liquid phase immerse method, thus SOFC composite anode material was synthesized. SrMoO3-YSZ that impregnated with GDC by hard template method was treated as the anode, YSZ as the electrolyte while LSM (La0.8Sr0.2MnO3-d) as the cathode, so that the solid oxide fuel cell could be assembled. At 800°C, the highest power densities of cells with the anode of SrMoO3-YSZ impregnated by GDC and the cell anode of SrMoO3-YSZ were 190.44mW•cm-2 and 98.06 mW•cm-2 respectively as methane was the fuels.
