The exponential growth in the requirement of fuel cells and batteries leads to increased demand for cobalt due its common use high-performance Li-ion high-temperature cells/electrolyzers. This sharp increment raises concern about availability limited reserves which can impact price cobalt. Moreover, geographic limitations resources may endanger whole supply chain. In addition all those, huge mo...

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 ...

Fuel cells convert chemical energy directly into electrical energy with high efficiencies and environmental benefits, as compared with traditional heat engines. Yttria-stabilized zirconia is perhaps the material with the most potential as an electrolyte in solid oxide fuel cells (SOFCs), owing to its stability and near-unity ionic transference number. Although there exist materials with superio...

a set of multicomponent perovskite oxide nanoparticles based on la1-xsrxco1-yfeyo3-δ(lscf) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (lt-sofc) as cathode materials.  the precursor materials used in this synthesis were lanthanum nitrate hexahydrate [la(no3)3.6h2o], strontium nitrate [sr(no3)2], cobalt nitrate hexahydrate [co...

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 ...

Ruddlesden–Popper type electrodes with composition La2CuO4−δ are alternative cathode materials for solid oxide fuel cells (SOFCs); however, the undoped compound exhibits low electrical conductivity potential applications, which is usually increased by alkaline-earth doping. A promising to doping modification of anionic framework halogen In this study, La2CuO4−0.5xAx (A = F, Cl, Br; x 0–0.3) com...

Symmetrical solid oxide fuel cells (S-SOFCs) are prepared via a facile one-step co-sintering method with highly reactive Sm0.2Ce0.8O1.9 (SDC) electrolyte and Sr2Fe1.5Mo0.5O6-δ (SFM) electrodes. The phase compositions microstructures studied by XRD, TEM, FESEM techniques, the electrolyte-supported single gas-tight SDC porous SFM-SDC electrode after at 1100 °C or higher temperatures for 4 h. In p...

We investigated the influence of a fuel change from pure hydrogen to hydrogen–ammonia mixture at different percentages on electrochemical behavior 50 mm in diameter Solid Oxide Fuel Cells (SOFCs) with sputtered thin buffer layers Gd-doped ceria, varying working temperatures 800 °C 650 °C. The results show that performances cells are not affected by for high (800 and 750 °C). As an example, powe...

Al2O3-forming austenitic (AFA) stainless steels are potential replacements for the existing balance of plant (BoP) components in solid oxide fuel cells (SOFCs). In this study, chromium (Cr) poisoning anode supported (ASCs) coupled with various alloys was analyzed by distribution relaxation times (DRT). The performance deterioration ASCs mainly attributed to increased polarization resistances ch...
