Description
Abstract:The sintering behavior of alkaline-earth-substituted lanthanum and yttrium chromites, which are candidates for the current interconnect in solid oxide fuel cells (SOFC) was investigated. Extensive commercialization of SOFC technology may involve co-sintering as a method to reduce production costs. Co-sintering will require that the interconnect material reaches high density (closed porosity) under conditions in which the air-electrode material, a manganite, maintains substantial porosity and remains stable. Therefore, ideal chromite compositions are those that attain greater than 94% of theoretical density in high PO[sub 2] atmosphere at temperatures near or below 1400[degree]C.
