摘要
Solid-oxide fuel cells (SOFCs) can be used for efficient energy conversion with a variety of fuels. The fuel tolerance of SOFCs is due primarily to the high operating temperature, which accelerates reactions in the fuel. However, the high temperature accelerates unwanted reactions and creates materials challenges, so intermediate-temperature SOFCs are being developed. Reduction of the operating temperature requires solid electrolyte materials with higher conductivities, which can create new compatibility issues. In this paper, materials challenges in the development of SOFCs will be discussed.
