Solid oxide structure of the cobalt-free composite has been exploited as a new cathode material for IT-SOFCs. The model system was synthesized using metallic material, which formed by solid-state reaction technique. generation Sm0.5Sr0.25Ba0.25FeO3-δ (SSBF) carried out during sintering process. weight loss and oxygen content were investigated thermal gravimetric analysis (TG). Meanwhile, X-ray ...

The usage of environment-friendly energy converter devices is getting more and attention as a result environmental crises regulations. SOFCs are among the highly efficient chemical to electrical converters. Thus, their effectiveness significant issue improve. To increase efficiency SOFCs, properties should be investigated. However, it costly time-consuming test all important characteristics sol...

Rare earth element-doped bismuth oxides with the fluorite structure (δ-Bi2O3) exhibit high oxygen ion conductivity at low temperature, which is promising electrolyte materials for intermediate-temperature solid oxide fuel cells (IT-SOFCs). However, traditional co-sintering process not applicable to manufacturing of IT-SOFCs using melting point Bi2O3-based electrolyte, while further high-tempera...

Lack of fundamental understanding the oxygen reduction reaction (ORR) hampers development effective metal oxide catalysts and advance low-temperature solid fuel cells (LT-SOFCs). In this study, we report Ba0.5Sr0.5Fe1–xSbxO3–δ (BSFSb, x = 0, 0.05, 0.1) cathodes designed from both theoretical experimental aspects to study a good relationship between material property enhanced ORR activity. The B...

Ni cermet anodes are commonly used in solid oxide fuel cells (SOFCs) [1–4], but there has been considerable interest in alternative oxide-based anodes [5]. The motivation for the alternative materials is to avoid problems with the Ni-based anodes, including susceptibility to coking in hydrocarbon and CO-rich fuels [6], poisoning by sulfur [7] and other fuel impurities [8], and degradation due t...

Mixed ionic/electronic conducting (MIEC) oxides, such as SrFeCo0.5Ox, (La0.6Sr0.4)(Co0.2Fe0.8)O3, and BaCeO3, are a class of ceramics that contain ionic and electronic carriers in high enough concentration that both forms of charge conduction are exhibited at high level, typically at temperatures in excess of 500°C. Because of their properties, the demand for MIEC oxide-based devices has grown ...
