      abstract     = {An electrode-supported solid oxide electrolysis cell (SOEC)
                      was operated for 6100 h with a current density of -0.75
                      A/cm2 at a temperature of 780 °C indicating high stability
                      and low voltage increase of 11 mV/kh. The cell consisted of
                      a 10 µm thick solid electrolyte (yttria-stabilised
                      zirconia, YSZ) and a diffusion barrier layer of gadolinium-
                      substituted ceria, a Ni/YSZ cermet as hydrogen electrode and
                      as mechanical support, and a La0.58Sr0.4Co0.2Fe0.8O3
                      perovskite as oxygen electrode. The electrodes as well as
                      the YSZ and CGO layers were deposited on the electrode
                      support by screen printing. Metallographic post-test
                      analyses showed no significant changes in microstructure
                      compared to the initial state. Investigations by means of
                      scanning electron microscopy, transmission electron
                      microscopy, energy dispersive X-ray spectroscopy indicate
                      material transport from the electrolyte into the diffusion
                      barrier layer and pore formation at the hydrogen electrode
