Fabrication and characterization of micro-tubular solid oxide fuel cells
… and magnesium-doped lanthanum gallate (LSGM), in which the single-phase perovskite LSGM region was determined. Yttria-stabilized zirconia (YSZ) and gadolinium doped ceria (CGO) electrolyte systems were also studied. Paste extrusion was identified as a suitable method for high-speed …

Layered perovskites as cathode materials for IT-SOFC
… (GDC) and La₀.₉Sr₀.₁Ga₀.₈Mg₀.₂O₃-δ (LSGM-9182) as the electrolyte material. Both oxides crystallize in tetragonal P4/nmm symmetry. The structural and phase stability has been confirmed up to 800 °C by High temperature XRD studies. The coefficient of thermal expansion (CTE) and oxygen …

Exploring Electrochemical Properties of Ti-Containing Oxides as Anodes for SOFCs
… ion conducting Sr- and Mg- co-doped LaGaO3 (LSGM) electrolyte. Smallest area specific resistance (ASR) of 1.1 cm2 was observed on the anode composition La2Ti2O7 + Fe + LSGM (1:1:1 vol. %) with 20 % porosity. Furthermore, gas phase K+/H+ exchange reaction was shown in K1.54Mg0.77Ti7.23O16 in …

Ceramic-Based Anodes for Solid Oxide Fuel Cells
… and Mn-doped LaGaO3 (La0.8Sr0.2Ga0.5Mn0.5O3-δ, LSGMn) has been synthesized by both GNC (glycine nitrate combustion) and SSR (solid state reaction) methods. XRD examination shows that the synthesized LSGMn has a pure single primitive cubic phase. Four-probe DC conductivity characterization …

Atomic scale diffusion in complex systems from first principles
Transport of point defects controls a variety of materials process such as precipitation, segregation of solutes to grain boundaries and surfaces, and macroscopic properties such as corrosion resistance and ionic conductivity. Therefore, a quantitative prediction of atomic scale transport is …
