摘要(Abstract)：

通过热分解法制备Ni0.75Fe0.25催化层,研究了不同螯合剂(柠檬酸,乙醇酸和D-葡萄糖酸)对催化层的结构及抗积碳性能的影响。结果表明:热分解法制得的晶相为Fe Ni3相,其结构及尺寸均与螯合剂有关。氧-程序升温氧化和拉曼光谱分析表明含D-葡萄糖酸的催化层具有最佳的抗积碳能力。采用D-葡萄糖酸改性催化层制作的单电池在650℃的甲烷燃料中最大功率达289 m W·cm-2。另外,该电池在甲烷燃料中以600 m A·cm-2的电流密度下运行9 h后电压仍保持初始电压的61%,而未改性的单电池电压相同运行条件下仅余53%。

关键词(KeyWords)： 催化层;螯合剂;热分解;相结构;抗积碳
