Correlation between degradation of cathode performance and chromium concentration in (La,Sr)MnO3 cathode

► Clarification between the Cr concentration in the (La,Sr) MnO3 cathode and degradation. ► Detection of low Cr concentration levels (ppm) in the porous (La,Sr) MnO3 by SIMS. ► Determination of deposited Cr amounts in the porous (La,Sr) MnO3/GDC interfaces.
