Abstract
Further cost reductions are necessary for the commercialisation of solid oxide fuel cells (SOFCs). The economically sensible methods of screen-printing and tape casting were used to fabricate green films that were subsequently sintered producing 4 cm x 4 cm planar Yittria-stabilized-Zirconia (YSZ)-based SOFCs. An anode-interlayer was also included in the cell design that increased interfacial bonding between the electrolyte and anode. The SOFCs were characterized using scanning electron microscopy and pressure drop measurements. The YSZ electrolytes were gas-tight and dense. These cells showed a power density of 0.14 W/cm2 when tested using a methane-water vapor fuel source at 800°CI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
