固体酸化物形燃料電池（SOFC）の構成材科と高性能化

摘要

Solid oxide fuel cells have been investigated as a highly efficient power generation system for the future. In addition to the highest efficiency among the generation system utilizing fossil fuels, the SOFC system is attracting with its excellent flexibility to various fuels; Internal reforming of hydrocarbon is possible by direct introduction of fuel into the cells. Recently, reduced .temperature operation of SOFC has been investigated for application to small scale generator due to ease of start-up shut-down. Development of more conductive electrolyte than yttria-stabilized zirconia and electrode materials are necessary for the realization of reduced temperature SOFCs.
