Abstract :
Anode cermets using various transition metals (Ni, Co, and Fe) and Ce0.8Sm0.2O2 − σ (SDC) were prepared and their catalytic activity for ammonia oxidation in solid oxide fuel cells (SOFCs) was investigated. Ni/SDC showed a high activity for hydrogen, but not for ammonia. Co/SDC showed a poor activity for both hydrogen and ammonia. Fe/SDC has the highest activity for ammonia oxidation in the temperature range of 973 to 1173 K. Moreover, it was found that Ni–Fe alloy/SDC anodes showed improved performance for ammonia oxidation. Ni40–Fe60/SDC anode showed the highest catalytic activity for NH3 oxidation, and therefore is promising for ammonia-fueled SOFCs.
