      abstract     = {Solid Oxide Fuel Cells (SOFCs) are able to use biogas or
                      natural gas with its main compound methane as fuel but
                      utilization of methane bears risks which can lead to early
                      performance loss. Application of a suitable type of methane
                      reforming as well as online monitoring tools and a holistic
                      knowledge about possible degradation mechanisms can limit
                      degradation rates. Here, we compare direct internal
                      reforming and external methane reforming on a large planar
                      SOFC with an active area of at different operating
                      temperatures and methane flow rates. To do so, the measured
                      temperature distribution, applied electrochemical impedance
                      spectroscopy and its advanced tool distribution of
                      relaxation times (DRT) as well as results from post mortem
                      microscopic analysis are used. We observed that the ohmic
                      resistance and high frequency peaks in the DRT spectra seem
                      to be influenced not only by the average cell temperature
                      but also by direct internal reforming (DIR) conditions.
                      Furthermore, we observed that high temperature gradients
                      induced by DIR could lead to or accelerate damages of the
                      cells structure and the sealing. The results presented in
                      this work are useful to control or manage safe SOFC
                      operation with C containing fuels for real world SOFC
