Status and prospects of intermediate temperature soid oxide fuel cells

Abstract

Compared with conventional electric power generation systems, the solid oxide fuel cell (SOFC) has many advantages because of its unique fetures. high temperature SOFC has been successfully developed to its commerical applications, but it still faces many problems which hamper large-scale cammercial applications of SOFC. To reduce the cost of SOFC, intermediate termperature solid oxide fuel cell (IT-SOFC) is presently under rapid developmetn. The status of IT-SOFC was reviewed with emphasis on discussion of their component mateials.
