      abstract     = {The cathode contact layer is a critical component in solid
                      oxide fuel cell stacks and one possible cause of
                      degradation. Even though this layer and its interfaces are
                      responsible for a large proportion of the ohmic resistance,
                      it is generally difficult to identify the degradation
                      without carrying out an autopsy of the stack. As a
                      non-destructive method, electrochemical impedance
                      spectroscopy is used in this work to investigate in-depth
                      the cathode contact and its evolution with the support of
                      distribution of relaxation time and differences in impedance
                      spectra analyses between 650°C and 800°C. By purposefully
                      building a stack with a reduced cathode contact area, the
                      electrochemical resistance of the contact is evaluated and
                      its frequency response identified. Through measurements at
                      various operating conditions the different peaks of the
                      distribution of relaxation time analysis are identified and
                      related to physical phenomena within the cell. These
                      findings are then applied to a stack with a standard contact
                      area in order to explain the degradation behavior observed
                      upon dismounting from the test bench.},
