Fuel cells are one of the most efficient and effective solutions to environmental problems high energy demand. They devices which change chemical into electrochemical energy, allowing much higher efficiency than conventional thermomechanical conversion methods. Lanthanum Strontium Cobalt Ferrite (LSCF) perovskites have been widely studied for application as cathodes in solid oxide fuel (SOFC) d...

The (Cu,Mn,Co)3O4 (CMC) spinel layer is useful in inhibiting Cr vaporization that deteriorates the solid oxide fuel cell performance. effectiveness of suppressing volatile species from metallic interconnects strongly dependent on density, which influenced by particle size distributions and agglomerations powders. Considering material properties were synthesizing conditions, this study elucidate...

reduction of exhaust emissions is a major research task in diesel engine development in view of increasing concerns regarding environmental protection and stringent exhaust gas regulations. simultaneousreduction of nox emissions and particulate matter is quite difficult due to the soot/nox trade-off and isoften accompanied by fuel consumption penalties. towards this aim, automotive engineers ha...

Abstract This paper mainly explores the anode properties of Co δ Fe 1-δ O x -Sm 0.2 Ce 0.8 1.9 (SDC) (δ=0, 0.2, 0.5, 0.8, and 1) for solid oxide fuel cell (SOFC). The composite materials were synthesized by sol-gel method, XRD technique was used to characterize structural properties. After H 2 reduction at 700 o C, oxides reduced Co, metal or Co-Fe alloy. symmetric cells fabricated with -SDC as...

Lanthanum strontium aluminum ferrite (La0.8Sr0.2Al0.2Fe0.8O3±δ-LSAF) perovskites are drawing attention as cathodes in solid oxide fuel cells (SOFCs). The structural properties of these materials mostly counting on the methods preparation. In this study, two different preparation namely hydrothermal and sol-gel were applied to prepare LSAF perovskite. characterization results including scanning ...

This article fundamentally reviews progress in the design and manufacturing of three-dimensional (3D) graphene-based nanocomposites for technical applications. The 3D graphene nanostructures have been manufactured using techniques like template method, chemical vapor deposition, sol-gel, freeze-drying, hydrothermal technique, other approaches. nanofoam has reinforced polymers to achieve superio...
