在823 ~ 973 K的温度范围内，研究了直接氨燃料SOFCs用镍基二元合金阳极的活性和稳定性。结果表明，在823 ~ 973 K温度范围内，Ni40-Fe60和Ni97-Mo3/SDC阳极的氨氧化活性高于Ni/SDC阳极。此外，Ni40-Fe60和Ni97-Mo3/SDC阳极在873 ~ 973 K的氨气氛中表现出比Ni/SDC阳极更高的稳定性。研究发现，在Ni40-Fe60和Ni97-Mo3/SDC阳极中，热循环引起的金属催化剂形状变化受到抑制。
The activity and stability of Ni-based binary alloy anodes for direct ammonia-fueled SOFCs were investigated in the temperature range of 823 to 973 K. It was found that the activities of Ni40-Fe60 and Ni97-Mo3/SDC anodes for ammonia oxidation were higher than Ni/SDC anode at temperature of 823 to 973 K. In addition, the Ni40-Fe60 and Ni97-Mo3/SDC anodes exhibited higher stability in a heat cycle test between 873 and 973 K in ammonia atmosphere than the Ni/SDC anode. It was found that the change in the shape of the metal catalysts induced by the heat cycle was suppressed in the Ni40-Fe60 and Ni97-Mo3/SDC anodes.
