INTERMEDIATE SOLID OXIDE FUEL CELLS, CHALLENGES AND OPPORTUNITIES FOR THE MATERIALS SCIENTIST

摘要

In an effort to address the cost and reliability issues, over the past few years, the development of Solid Oxide Fuel Cells (SOFCs), has been towards the reduction of operation temperature into the intermediate temperature (IT) regime (500 - 700℃). The intermediate temperature operation requires (1) an extremely strict material selection, which allows electrode kinetics and internal resistance similar to those occurring in the high temperature regime (900 - 1000℃); (2) feasible techniques to build devices so that each component in the SOFC can function efficiently. It is the intent of this review to give an overview of the challenges and opportunities that the intermediate temperature SOFCs presents to the materials scientists.
