These experimentally based findings were obtained by direct comparison of cathode performances measured on a segmented test arrangement enabling the independent control of four cathodes, with different thicknesses, on an anode-support. The cathode thickness-dependent performance degradation was correlated to deliberate poisoning by volatile Cr species stemming from the test arrangement.Solid Oxide Fuel Cell (SOFC)CathodeDegradationCr-PoisoningEnergy Dispersive X-ray spectroscopy (EDS)text::journal::journal article::research article
