“…Similar phase diagrams were constructed by using reported thermodynamic properties for the Ce-Ni and Gd-Ni systems. 25,26 Ni system has liquid in the Ce-rich region, and the Gd-Ni system also shows liquid formation in the eutectic composition area. In Figure 7, no solid solutions are treated so that liquid phases are explicitly indicated as phase composition and "(l)".…”

The electrochemically induced interaction between Ni and GDC was investigated using a network-shaped Ni electrode on a dense interlayer of gadolinia-doped ceria (GDC) with yttria-stabilized zirconia (YSZ) electrolyte. The sample with a platinum counter electrode and a reference electrode was treated at 1173 K for 5 h with flowing 1% H 2 O -H 2 gas mixture under different applied potentials. The morphology of Ni electrode changed when potential was applied. A large number of ceria particles in several tennanometer size was precipitated on the Ni surface. The Ni-GDC interaction became more significant with increasing applied potential. The relationship between electrochemically induced morphological change and overpotential-induced oxygen potential change is discussed.
