Sulphur poisoning of the SOFC cathode material La sub(0.6)Sr sub(0.4)CoO sub(3- delta )

The oxygen exchange kinetics of La sub(0.6)Sr sub(0.4)CoO sub(3- delta ) was investigated at 700 degree C and p(O sub(2)) = 0.10 bar by in-situ conductivity relaxation measurements. The experiments were performed for 1000 h in an O sub(2)-Ar atmosphere with and without 50 ppm SO sub(2). For post-tes...
