Abstract

Chromium poisoning was investigated at the cathode/ Gd0.2 Ce0.8 O1.9 electrolyte interfaces under cathodic polarization by using a preoxidized Cr metal. The concentration levels of Cr in the porous cathodes [La0.8 Sr0.2 MnO3 (LSM) and La0.8 Sr0.2 FeO3 (LSF)] was first determined by secondary ion mass spectrometry. Maxima of Cr concentration were observed at the LSM/electrolyte interfaces (about 1000 ppm). On the other hand, no maxima of Cr concentration were observed with homogeneous distribution of Cr (1000-1700 ppm). The amount of Cr deposited in the LSF cathode is estimated to be about 21% of the supplied Cr and is about 1.6 times higher in the LSM. © 2009 The Electrochemical Society.
