Abstract
Cermet anodes composed of Ni and Dy2O3 have been applied as anode for intermediate-temperature solid oxide fuel cells. Although the oxide ion conductivity of Dy2O3 is negligible compared to that of doped ceria (DCO), Ni–Dy2O3 cermet anodes have displayed very high performance comparable to that of the commonly used Ni–SDC cermet anode. Temperature programmed reduction study suggests that the catalytic activity of the Ni–Dy2O3 cermet might be originated from the hydrogen adsorption ability on the Dy2O3 surface, promoting hydrogen spillover process, and consequently enhancing the electrochemical oxidation of the fuel. Further, the electrochemical catalytic activity of Au-based cermet anode confirms that hydrogen adsorption capability is as important as oxygen-ion conductivity for the ceramic component in a cermet anode.
