      abstract     = {Electrochemical impedance spectroscopy is a widely used
                      tool to study electrochemical reactions in batteries, fuel
                      cells and other electrochemical energy conversion devices.
                      However, conduction processes in the electrolyte of high
                      temperature fuel or electrolysis cells (SOFC / SOEC) are
                      inacessible during operation, severely restricting the
                      information that can be obtained about performance and
                      degradation of the electrolyte. Using the distribution
                      function of relaxation times (DRT), we study the ionic
                      conduction properties and degradation phenomena in
                      multi-layered solid electrolytes, ex situ and at low
                      temperatures. The investigation of full cells in air enables
                      a detailed analysis of the conductivity of supported
                      electrolytes as thin as 1 μm, as well as the relative
                      contributions of multilayered electrolytes. Furthermore,
                      three case studies are presented concerning the degradation
                      mechanism in SOFC and SOEC operation, showcasing the ability
                      of this technique to distinguish the effects of grain
                      boundary contamination, formation of solid solutions and the
                      formation of porosity on the ionic conductivity of thin,
                      supported electrolytes.Keywords: SOFC; SOEC; Impedance
