      abstract     = {The utilization of novel fuel electrode materials could be
                      a valid solution to improve the durability of solid oxide
                      electrolysis cells and the path way for worldwide
                      commercialization. Especially, Ni-free fuel electrodes are
                      promising to eliminate Ni migration as an important
                      degradation mechanism. Gadolinium doped ceria (GDC) is an
                      interesting material due to its good stability towards
                      carbon deposition and the possibility to host
                      electrocatalysis in electrolysis conditions. The present
                      study aims to investigate the performance, electrochemical
                      processes and long-term stability of pure GDC fuel electrode
                      single cells. The results show a lower degradation rate in
                      comparison to similar produced Ni-GDC single cells in steam
                      electrolysis conditions and around 70 $\%$ of its
                      performance. Furthermore, the charge transfer in the GDC
                      fuel electrode is identified as the reaction
                      rate-determining process in the GDC fuel electrode single
                      cells.},
