Factors Influencing Thermal Stress Development in Solid Oxide Fuel Cells

Abstract

Solid oxide fuel cells (SOFCs) are favorable alternatives to fossil fuels because SOFCs have minimal carbon emission and can thus provide clean sustainable energy. They also have higher power-generation efficiency than traditional energy sources. However, improvements in the power and performance of SOFCs have caused the SOFC stack to be subjected to high thermal load and thermal stress, which should be minimized to prolong the stability and durability of a fuel stack. This paper presents a review on SOFCs from the perspective of thermal stress and its influencing factors.
