The Yttria stabilized Zirconia (YSZ) is a standard electrolyte for solid oxide fuel cells (SOFCs), which are potential candidates for next generation portable and mobile power sources. YSZ electrolyte thin films having a cubic single phase allow reducing the SOFC operating temperature without diminishing the electrochemical power density. Films of 8 mol% Yttria stabilized Zirconia (8YSZ) and fi...

A novel route to fabricate nano-fiber anode material for solid oxide fuel cells (SOFCs) is presented. Firstly, uniform nano-fibers of 8 mol % Yttria Stabilized Zirconia (8YSZ) were formed in an electrospinning process; then, these electrospun fibers were calcined at temperatures up to 1300 °C; and finally the ceramic 8YSZ nano-fibers were coated with nickel in an electroless plating process. Th...

The microstructural and electrochemical properties of anodes obtained by impregnation the La 0.4 Sr 0.6 Ti 0.8 Mn 0.2 O 3±d (LSTM) oxide system into two types anode substrates such as Ni/ 8YSZ substrate (Ni (E)/ 8YSZ) partially Ni removed (Ni(R)/8YSZ) were investigated in order to apply them material for solid fuel cells. All samples with LSTM impregnated on (R)/ show higher electrical conducti...

This work presents a solid-state ionic-based device to selectively detect C2H4 in car exhaust gases. The sensor consists of 8YSZ as the electrolyte and two electrodes: Fe0.7Cr1.3O3/8YSZ LSM/8YSZ. main aim this is optimize catalytic behavior working electrode reduce cross-sensitivity toward CO H2O. Several catalyst nanoparticles were infiltrated tailor adsorption electrochemical oxidation proper...

Biaxially-textured epitaxial thin-film hetero-structures of ceria and 8 mol% yttria-stabilized zirconia (8YSZ) were grown using Pulsed Laser Deposition (PLD) with the aim to unravel the effect of the interfacial conductivity on the charge transport properties. Five different samples were fabricated keeping the total thickness constant (300 nm) but with a different number of hetero-interfaces (b...

Giant electrostrictors based on oxygen deficient fluorites are of great technological and scientific interest due to their unusual electromechanical properties. It is, however, still not clear whether solid solutions between different can affect the electrostrictive In this work, we investigated response four 10 mol% gadolinium-doped ceria (GDC10) 8mol% yttria-stabilized zirconia (8YSZ), corres...

The purpose of this paper is to study the thermal shock resistance and failure mechanism La2Ce2O7/8YSZ double-ceramic-layer barrier coatings (LC/8YSZ DCL TBCs) under extreme temperature gradients. At high surface temperatures, infrared measuring modules were used determine cycling life insulation LC/8YSZ TBCs gradients by an oxygen–acetylene gas flame testing machine. A viscoelastic model was o...

The maximum power density of SOFC with 8YSZ electrolyte as the function of thickness was calculated by integrating partial conductivities of charge carriers under various DC bias conditions at a fixed oxygen chemical potential gradient at both sides of the electrolyte. The partial conductivities were successfully taken using the Hebb-Wagner polarization method as a function of temperature and o...
