Three long-term experiments have been performed in SOEC and SOFC modes at different operating temperatures. The durability tests confirm a higher degradation electrolysis mode with respect to fuel cell operation. In addition, larger increase of the ohmic resistance is observed for operated temperature mode. oxygen electrodes pristine tested cells characterized by synchrotron X-ray micro-diffrac...

Solid Oxide Fuel Cells (SOFCs) can convert chemical energy into electrical energy, with high conversion rate, safe operation, no pollutant emissions, and is one of the most potential new power generation devices in future. However, at low medium temperature (below 800℃), cathode impedance SOFCs will increase sharply, resulting adverse effects on cell performance. Finding materials that work key...

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...

The present study focuses on an alternative structured oxygen electrode for solid oxide electrolysis cells (SOECs). La2NiO4+δ nickelate, LNO, was selected with respect to its mixed electronic and ionic conductivity good chemical stability. Complete single were built using screen printing of LNO LaNi0.6Fe0.4O3 (LNF) layers a standard hydrogen supported half cell consisting porous NiO-YSZ layer, ...

Nano-structured lanthanum strontium cobalt ferrite, La0.6Sr0.4Co0.2Fe0.8O3 (LSCF), was successfully synthesized via co-precipitation method using metal nitrates as starting materials. Effects of precipitating agent and calcination temperature on the phase composition and morphology of synthesized powders were systematically studied using X-ray diffraction (XRD) and field emission scanning elect...

The present paper aims at investigating the applicability of hybrid cells in the series model for pollution transport inside the layered porous media. For this purpose, four layers of rock material have fallen inside the experimental flume, with eight sensors installed longitudinally inside the media to obtain experimental BTCs. In order to measure time parameters of the model, named , two diff...
