...Zhenwei Wang; Masashi Mori The air-sintering characteristics and electrical conductivity of (Sr 1−x La x )TiO 3 perovskites (0 ≤ x ≤ 0.3) synthesized by the citric acid method were evaluated in terms of their use as interconnect materials in solid oxide fuel cells. A single perovskite phase of (Sr...

... of B-Site vacancies in the perovskites through charge compensation. It was found that A-Site and B-Site deficiencies increase the density of (Sr 1 − x La x ) 1 − y Ti 1 − z O 3 perovskites. These characteristics may prove useful in the development of solid oxide fuel cell interconnect materials. 28...

...Masashi Mori; Zhenwei Wang; Nobuyuki Serizawa; Takanori Itoh The compatibility of SrTi 1− x Co x O 3 perovskites (0 ≤ x ≤ 0.2) was evaluated for use as interconnect materials in solid oxide fuel cells (SOFCs). Although SrTi 1− x Co x O 3 perovskites have a single perovskite phase in the range of 0...

... ) 3 O 4 spinel compounds are generated on the surface oxides. Other spinels that contain Cr, Mn, Fe, and Ni are also formed on it; the compositions depend on the composition of the steels and any other materials that are in contact with the interconnects. Accordingly, the role of spinels...

...) and interconnects made by ferritic stainless steels. These metallic materials match very well the thermal expansion behavior of the ASCs and can be manufactured and formed using cheaper and easier processes than ceramics or chromium alloys. Nevertheless, some problems remain to be solved with these components...
