Catalytic Behavior of PdONiOSDC composites for partial oxidation of methane: Application as anodes of single-chamber IT-SOFCs

Mostrar todas las versiones(2)

PdONiOSDC composites (SDC: Sm2 O3 -doped Ce O2) have been proposed to be excellent anodes for single-chamber, intermediate-temperature solid oxide fuel cells (SC-IT-SOFCs) operated under mixtures of C H4 and air, reaching high power densities at relatively low working temperatures. In this work we e...

Anodes Catalyst activity Catalytic oxidation Nickel oxide Palladium compounds Catalytic behavior Catalytic properties High power density Intermediate temperature solid oxide fuel cell Partial oxidation of methane Partial oxidations Reaction temperature Working temperatures Solid oxide fuel cells (SOFC) PdONiOSDC composites (SDC: Sm2 O3 -doped Ce O2) have been proposed to be excellent anodes for single-chamber, intermediate-temperature solid oxide fuel cells (SC-IT-SOFCs) operated under mixtures of C H4 and air, reaching high power densities at relatively low working temperatures. In this work we evaluated the catalytic activity of these composites in the partial oxidation of C H4, finding that their high performance is due to the excellent catalytic properties of these materials. The effect of the addition of PdO was investigated by analyzing NiO/SDC and PdONiOSDC composites under different reaction temperatures and C H4: O2 ratios. Finally, PdONiOSDC composites were evaluated under operation in SC-IT-SOFCs similar to those reported in the literature using SDC electrolytes and Sm0.5 Sr0.5 Co O3 cathodes.
