Ceramic-Based Anodes for Solid Oxide Fuel Cells
… fuels. In this study, both LaGaO3 and LaCrO3-based¬ systems have been explored as anode materials for SOFCs. The results have shown that these two systems are promising anode materials by judicious selection of dopants on both A- and B- sites of the perovskite structure. </p> <p>For the …

All-electron GW calculations for perovskite transition metal oxides
… GW calculations for the three band insulators LaCrO3, LaMnO3, and LaFeO3 are carried out. Results from DFT calculations employing the generalized-gradient approximation with the PBE functional or results obtained from calculations using the hybrid-functional HSE are used as starting point to …

Li₂0₂ in Li-0₂ batteries : catalytic enhancement of electrochemical oxidation and thermophysical transformations
… systematically investigated. It was found that LaCrO3, reported with the lowest activity in aqueous OER, shows a threefold higher activity compared to BSCF, reported with two orders of magnitude higher activity in aqueous OER. We postulate that efficient catalysts affect the surface energy …

Catalysts and materials development for fuel cell power generation
… included ceramic nanocomposite anodes, CeO2/LaCrO3 and Sm-CeO2/La-CaTiO 3. The former gave rise to Cr(VI) formation due to the intimate mixing of the different ceramic nanoparticles. The latter was limited in applicability due to its low electrical conductivity. Thus, 2 a novel cermet system, …
