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

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...
