      abstract     = {In this work we investigate the effect of Cr-poisoning at
                      OCV-condition by means of electrochemical impedance
                      spectroscopy (EIS). The anode-supported cell (ASC) is
                      operated in Cr-free environment for the first 70 h of the
                      cell test at 800 °C supplying air to the cathode and a
                      varying mixture of H2O/H2 to the anode. The performance of
                      the cell is determined by current-voltage (CV) measurement
                      after the start up. After an operating time of 70 h in the
                      absence of chromium species a Cr-source was switched on by
                      passing the oxidant (air) through a Crofer22APU powder bed.
                      In order to determine the degradation caused by Cr-poisoning
                      electrical impedance spectra are collected at every 29 h
                      of operating time. After further 275 h at OCV-condition in
                      the presence of Cr-source another CV-curve is measured. A
                      detailed analysis of the measured impedance spectra by the
                      distribution of relaxation times (DRT) enables a separation
                      of the cathode polarization resistance. During the Cr-free
                      operation the cathode polarization shows a constant value.
                      After the Cr-source is switched on a strong increase of the
                      cathode polarization resistance is observed. This unique
                      result shows clearly that Cr-poisoning of an
                      LSM/8YSZ-cathode already takes place at OCV-condition.},
