Development of Microtubular SOFCs

Microtubular solid oxide fuel cells (SOFCs) have successfully demonstrated their advantages over conventional (planar) SOFCs, such as high thermal stability during rapid heat cycling and large electrode area per volume, which enables one to realize SOFC systems applicable to portable devices and auxiliary power units for automobile. In this study, the fabrication method of the microtubular SOFCs was examined. Shrinkage behavior and the microstructure of electrolyte/anode as a function of sintering temperature were shown and correlated with densification of the electrolyte during cosintering process.

Mass Flow Rates

This paper explores the potentials of solid oxide fuel cells (SOFCs) as 3 kW auxiliary power units for trucks and military vehicles operating on diesel fuel. Various issues are discussed, e.g., the requirements and specifications for the unit as well as the advantages, challenges, and development issues for SOFCs in such applications. System design and analysis are carried out. The major component of the system is the fuel cell stack. The calculations are performed for two voltage systems 12/14 V and 36/42 V, respectively. The influences of others parameters like the mass flow rates of air and gases, water production and heat production are also evaluated for the two voltage systems.

High Thermal Shock Resistance

Microtubular solid oxide fuel cells (SOFCs) are considered to be ideal for application such as auxiliary power units due to their high thermal shock resistance and their compactness (high volumetric power density). Thus, it is of importance to understand the performance of the cell under actual fuel-fed condition. In this study, we demonstrate the performance of the microtubular SOFCs using a forming gas and a gas reformed from ethanol-water mixture.
