Abstract

Defect fluorite, Bi-doped Pr₆O_11, was studied as a cathode and it was found that Bi doped Pr₆O₁₁ exhibits high surface activity for the cathode reaction, and an all-fluorite concept SOFCs is successfully demonstrated by using Ce_0.6Mn_0.3Fe_0.1O₂ for anode. Diffusivity and surface activity in Bi doped Pr₆O₁₁ was further studied with ¹⁸O₂-¹⁶O₂ gas phase exchange and a surface activity was competitively high with that of La_0.6Sr_0.4Fe_0.8Co_0.2O₃ (LSFC), and this high surface activity is a result of the large oxygen vacancy in Pr₆O₁₁. The power generation property of the cell was also examined by using C₃H₈ and the power density of 0.4 W/cm² was exhibited when dry C₃H₈ was directly used for a fuel because of decreased IR loss.
