Conductive oxides are widely studied as cathode materials for electrochemical cells, such solid oxide fuel cells (SOFCs), because of their chemical stability and high electrical conductivity at temperatures (800–950 °C). The is a key component SOFCs, accounting the greatest resistance loss among SOFC components. It important to precisely determine material, but it difficult achieve consistency ...

High power density operation is essential for cost reduction in solid oxide fuel cells (SOFCs), and thus the present work proposes a highly active Gd0.5Sr0.5CoO3−δ (GSC) Ce0.8Gd0.2O1.9 (GDC) nanocomposite cathode intermediate-temperature SOFCs. Its structure formed by using GSC-GDC particles synthesized via spray pyrolysis, which produces uniform-sized secondary consisting of nano-sized GSC GDC...

Most world country dependent on foreign oil to make things working, which means political disputes or any between countries can result in energy crunches. The negative changes that occur the global climate and environment due burning of fossil fuels, stimulate search for modern environmentally friendly sources production. In addition, continued concern about storage processing nuclear waste may...
