Cover Story: This paper investigates the influence of the morphology of cermet anodes for proton ceramic fuel cells (PCFCs) on their anodic performance. Ni-cermet anode films based on BaCe0.4Zr0.4Y0.2O3−δ (BCZY) and Gd0.1Ce0.9Ox (GDC), that is, 60 wt%Ni–BCZY, 60 wt%Ni–BCZY–GDC, and 60 wt%Ni–GDC, were formed on BCZY electrolyte supports. The Ni grain size in these films after sintering at 1450 °C was around 2 µm. The addition of GDC did not affect the Ni grain size in the case of the porous BCZY matrix. The anodic properties greatly depended on the oxide-phase composition and worsened with an increase in the GDC content. This probably occurred because the addition of GDC, which has low proton conductivity, inhibited the proton conduction path of BCZY, reducing three-phase boundaries in the anode bulk. View this paper
