Planar Solid Oxide Fuel Cells: From Materials to Systems

摘要

In this article, recent technology updates regarding planar type solid oxide fuel cells (SOFCs) are reviewed. Intermediate-temperature operation of SOFCs is a recent R&D trend because of such advantages as cost effectiveness due to the use of low-cost metallic parts and thermal cycle ability. Materials are related to cell performance and operating temperatures, and stack designs are related to hot modules and system design. Also, “reforming” is an important issue for the achievement of high-efficiency SOFC systems.
