在973 ~ 1173 K温度范围内研究了过渡金属（Cr和V）渗Ni/Sm掺杂氧化铈（SDC）金属陶瓷阳极对NH3的氧化活性。3at.%相对于总金属组成添加Cr和V改善了NH3氧化的阳极活性。讨论了镍基二元阳极的阳极活性与添加过渡金属的金属-氮结合能之间的关系，这是实现直接氨燃料SOFC高活性阳极的关键。
The activity of transition metals (Cr and V) infiltrated Ni/Smdoped ceria (SDC) cermet anodes for NH3 oxidation was investigated at 973 to 1173 K. The 3 at.% addition of Cr and V with respect to the total metal composition improved the anode activity for NH3 oxidation. The relationship between the anode activity of the Ni-based binary anode and the metal-nitrogen binding energy of the added transition metal, which is a key to realize the highly active anode for direct NH3-fueled SOFCs, is discussed.
