001019740 520__ $$aThe 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.
