Development of metal-supported solid oxide fuel cells

Abstract

Different from the common all-ceramic counterpart, the metal-supported solid oxide fuel cells (SOFCs) use a porous alloy to support the functional anode-electrolyte-cathode thin layers. The SOFCs have some advantages like excellent structural robustness, high tolerance toward to rapid thermal cycling, simplified stack assembling and reduced materials cost. This paper briefly reviews the some related aspects on the materials selection and cell fabrication for the unique design as well as the recent development of the metal-supported SOFC technology.
