英文摘要	以壳聚糖/硝酸铁凝胶为前躯体，实现了含氮高分子与金属盐的均匀混合，将凝胶冷冻干燥处理后，经过热处理和酸刻蚀得到了成分及微结构更加均匀的铁氮掺杂多孔碳片. 铁氮掺杂多孔碳片与商业铂碳相比，具有更高的起始电位，半波电位和优秀的循环性能，在碱性燃料电池的测试中实现了更高的功率密度. 铁氮掺杂多孔碳片出色的氧还原电催化性能归因于铁在壳聚糖中的原子级分散所导致的均匀分布的铁氮碳催化活性位，大的比表面积和均匀的孔道分布.; The chitosan/nonahydrate gel was used as a precursor to realize the uniform mixture of N-polymer and metal salt. After lyophilization treatment, the gel went through heat treatment and acid etch. Accordingly, the Fe-N-doped porous carbon sheet with homogenous composition and microstructure was prepared. Compared with the commercial Pt/C catalyst, the Fe-N-doped porous carbon sheet exhibited more positive onset potential and half-wave potential, higher current density, and especially, excellent durability. The power density of 318 mW·cm-2 was obtained in alkaline fuel cell with the Fe-N-doped porous carbon sheet as a cathode catalyst, which is higher than 267 mW·cm-2 with the Pt/C as a cathode catalyst. The improved cell perforence with the Fe-N-doped porous carbon sheet might be contributed to the atomicaly dispersed iron in chitosan, which results in the homogenous dispersion of Fe-N-C active site, high specific surface area and pore size distribution.; 中科院“百人计划”和基金委优青 (21422108)资助; 作者联系地址：1. 吉林大学材料科学与工程学院，汽车材料教育部重点实验室，吉林长春 130022；2. 中国科学院长春应用化学研究所，稀土资源利用国家重点实验室，吉林长春 130022; Author's Address: 1.
