The chemical modification of perovskites is one the most effective design strategies for electrode materials solid oxide cells. In this work, tungsten doping in Sr2Fe2−xWxO6−δ shows a significant impact on their physicochemical properties, and it leads to substantial change electrochemical properties air reducing conditions, with Sr2Fe1.8W0.2O6−δ (Rp = 0.06 Ω cm2 at 800 °C stable 100 h air) Sr2Fe1.6W0.4O6−δ 0.56 over 5 vol% H2/Ar) being best fuel candidates, respectively. We have proposed an...
Cu-content La1-xSrxNi1-yCuyO3-δ perovskites with A-site strontium doping have been tuned as cobalt-free cathode materials for high-performance anode-supported SOFCs, working at an intermediate-temperature range. All obtained oxides belong to the R-3c trigonal system, and phase transitions from space group a Pm-3m simple perovskite observed by HT-XRD studies. The substitution of lanthanum lowers transition temperature, while increasing thermal expansion coefficient (TEC) oxygen...

Solid Oxide Fuel Cells (SOFCs) are one of the most attractive energy conversion and storage devices, which can be applied for decentralized applications. However, high operating temperature making SOFCs still unmarketable, indicates that lowering working while maintaining a high-power output is very crucial. For Intermediate-Temperature (IT-SOFCs), new cathode materials with electrocatalytic activity stability necessary to provide stable performance cells. Perovskite-structured oxide (ABO...
Solid oxide cells (SOCs) offer great promise for efficient energy generation and storage in a variety of applications. Symmetrical SOCs with identical anode cathode materials configuration favoring an reversible operation the cells, allow both electricity production from traditional renewable sources fuel cell mode, clean, (in reverse/electrolysis mode). In addition, symmetrical design is particularly advantageous, including: decreased number components, simplification fabrication process...
