Review of the micro-tubular solid oxide fuel cell (Part II: Cell design issues and research activities)

Micro-Tubular Solid Oxide Fuel Cells (MT-SOFCs) are small tubular shaped, ceramic based, electrochemical electrical power generation devices that operate at high temperatures and can potentially be fuelled with hydrocarbon based fuels. In comparison to Part I of this review paper series, which considered stacks of MT-SOFCs, part II aims to gather and arrange information regarding MT-SOFCs, in order provide a state of the art account for those entering the field or those interested in the technology. This review paper deals with MT-SOFC; reported architectures, geometry and cost considerations, details regarding individual cell components, reported methods of producing MT-SOFCs, reports and details regarding MT-SOFCs and reforming, reported novel modes of operation, reports regarding the mechanical properties of MT-SOFCs, comment and reports regarding SOFC/MT-SOFC reliability and durability, and finally, comment and conclusions.
