摘      要：We have investigated the effect of Cr poisoning on various cells which consist of either LaNi0.6Fe0.4O3 (LNF) or La0.8Sr0.2MnO3 (LSM) as a cathode and either yttria- stabilized zirconia (YSZ) or alumina- doped scandia stabilized zirconia (SASZ) as the electrolyte. It was found that the cathodic overvoltage was almost the same for cells with LNF cathodes, either in the presence or absence of Cr- containing alloy (Inconel 600). LSM cathodes in the presence of Inconel 600 exhibited a very steep increase in voltage curves after applying the current. These results indicate that the LNF cathode is electrochemically stable for Cr poisoning compared with the LSM cathode. (c) 2005 The Electrochemical Society.
