Review of the Application of Metal-Supported Solid Oxide Fuel Cell in the Transportation Field

Abstract As a promising clean energy conversion device, solid oxide fuel cells (SOFCs) could efficiently utilize multiple fuels and have been applied in stationary power generation and other fields. However, the high operating temperature limits the use of SOFCs in the transportation sector. Consequently, reducing the operating temperature is a key focus in SOFCs development. In recent years, metal-supported SOFCs (MS-SOFCs) have received significant attention because of intermediate operating temperatures. MS-SOFCs offer advantages such as simple and reliable sealing, rapid start-up, and high power density, making MS-SOFCs a promising option for transportation applications. However, for commercial applications, the methods to enhance performance, improve durability and mitigate degradation need to be further studied. This paper comprehensively reviews the state of the art approaches to performance improvement, durability under various conditions and different fuel reforming methods. Finally, it highlights the prospects and challenges for future advancements in this field.
