摘要

This R&D has focused on reducing the cost of solid oxide fuel cell (SOFC) modules through the application of lanthanum-concentrate to the separator and/or the cathode. A database, which is described in this report, was created with respect to the solution limit, relative density, and thermal expansion behaviors of lanthanum chromite perovskite when light rare earth (Ln, Ln=Ce, Pr, Nd) elements were substituted for high- purity lanthanum, in order to examine the effects of various combinations of Ln elements on the separator. Most (La_(1-x)Ce_x)_(1-y)AE_yCrO_3 samples contained a small amount of impurities in addition to the perovskite phase. AE(AE=Ca, Sr) doping of La_(1-x)Ln_xCrO_3 (Ln=Ce, Pr, Nd) increased their TECs, whereas the rare earth metal-doping of La_(1-y)AE_yCrO_3 decreased its TEC.
