      abstract     = {Metal-supported fuel cells (MSCs) are promising candidates
                      for non-stationary applications like auxiliary power units
                      or range extenders in battery electric vehicles. They are
                      attractive due to their potential to withstand fast thermal
                      cycles and vibrations during cell operation. In addition,
                      they have to withstand redox cycles, which might occur
                      during start-up and shut-down of the fuel cell stack.
                      Recently, a novel nickel/gadolinium doped ceria anode
                      (Ni/GDC) was introduced in the metal-supported fuel cell
                      concept of Plansee SE which almost tripled current density
                      compared to the standard cell concept with a Ni/YSZ anode.
                      In the present work, both cell concepts were compared
                      regarding their ability to withstand harsh redox cycles.
                      Therefore, after initial check at 750 °C, cell performance
                      of button cells after controlled redox cycles was
                      investigated at different temperature steps respectively.
                      Re-oxidation temperature of the anodes was varied between
                      300 and 700 °C for 10 min in air. Afterwards, reduction of
                      the anode was conducted by purging anode side with N2 for 10
                      min and then going back to standard cell operation
                      conditions with H2 supply. The response of cell performance
                      on redox cycling was recorded continuously. While standard
                      MSCs with Ni/YSZ anode showed a strong degradation after a
                      few cycles if the oxidation was conducted at temperatures
                      above 600 °C, novel MSCs with Ni/GDC anode showed a
                      remarkable resistance against re-oxidation. For a deeper
                      understanding of this behavior, microstructural
                      investigation of the Ni/GDC anode and the adjacent
                      electrolyte was performed within the tested cells by FE-SEM
                      and FIB-SEM 3D structure analysis. Furthermore,
                      electrochemical behavior of Ni/GDC anode was investigated at
                      a larger cycle number of up to 50 redox cycles with 2 h air
                      supply each.},
