摘　　要：直接碳燃料电池(DCFC)是一种清洁高效利用碳资源发电的装置。其因能量转换率高,对环境污染小,燃料选择范围广等优点获得了越来越多的关注。DCFC的性能与使用的燃料密切相关,为了探究燃料对DCFC的影响,本文分别阐述了石墨、炭黑、中密度纤维板、生物质、煤、活性炭的特性及改性方法,分析讨论了燃料表面含氧官能团以及燃料中的金属催化剂对阳极电化学反应的促进作用,发现燃料表面化学性质要比比表面积更加重要。同时,本文也提出了对生物质这一优良的可再生资源的期待,为未来DCFC燃料的发展提供参考。The direct carbon fuel cell(DCFC) is a clean and efficient power generation device using carbon resources. It has attracted more and more attention due to its high energy conversion efficiency, low environmental pollution and wide range of fuel selection. The performance of DCFC is closely related to the fuel used, in order to explore the influence of fuel on DCFC, the characteristics and modification methods of graphite, carbon black, medium density fiberboard, biomass, coal and activated carbon are expounded in this paper. The surface oxygen-containing functional groups and the promoting effect of metal catalysts in fuel on anode electrochemical reactions are analyzed and discussed. It is found that fuel surface chemical properties are more important than the specific surface area. Simultaneously, this paper also puts forward the expectation of biomass as an excellent renewable resource, it will provide a reference for the development and utilization of DCFC fuel in the future.
