The Properties and Performance of Micro-Tubular (Less Than 1 mm OD) Anode Supported SOFC for APU-Applications

摘要

Solid Oxide Fuel Cells (SOFCs) consisting of durable ceramic components can be considered nowadays as the most promising fuel cell systems for alternative sources of energy due to their high electrical conversion efficiency, superior environmental performance, and fuel flexibility. In comparison to conventional SOFCs, micro tubular SOFCs have many advantages such as high resistance to thermal shock and higher power densities reaching 0.3 W cm-1 at 550°C. Recent improvements of the mechanical and electrochemical properties at reduced operating temperatures allows the use of cost-effective materials for interconnects and balance of plant.
