摘要

Lowering the operation temperature of Solid Oxide Fuel Cells (SOFCs) offers a number of advantages including relaxing of the material selection requirements for sealing and interconnection and promoting application of SOFCs in small units such as in dispersed power generation systems and transport (1). These cells operate by means of a ceramic electrolyte at temperatures typically above 500°C in order to achieve sufficient values of ionic conductivity. Ionic conduction is provided by oxygen ions in the most widely used solid electrolytes of mixed oxides of yttria/zirconia (YSZ) or ceria/gadolinia (CGO). Lower temperature operation also implies higher thermodynamic efficiencies due to higher Nernst voltages.
