- •
Some basic oxide-based additives are introduced into the Ni–SDC cermet anode.
- •
CaO and BaO modifiers could increase the coking resistance of Ni–SDC toward methane.
- •
CaO had a positive effect on cell performance while BaO had a negative effect.
- •
High power output of 708 mW cm−2 was obtained with methane fuel at 650 °C.
- •
The solid oxide fuel cell with CaO modified Ni–SDC anode delivered good stability.
