摘　　要：固体氧化物直接碳燃料电池(solid oxide direct carbonfuel cell,SO-DCFC)在煤炭清洁利用方面具有独特优势,近年来受到研究人员的广泛重视。在对SO-DCFC基本概念与特点介绍基础上,对其中3个重要研究内容,即阳极反应机制、机制建模与模拟、及性能改进与优化方面的研究现状和进展进行了综述分析,指出SO-DCFC阳极反应机制与碳燃料和阳极接触方式密切相关,对其性能改进极为重要;碳燃料与阳极直接物理接触时基本不发生碳的直接电化学反应,碳燃料与CO2的气化反应是影响SO-DCFC性能的速率控制步骤;目前SO-DCFC模拟研究工作较少,应加强SO-DCFC机制建模与模拟工作;通过引入碳燃料催化气化和抑制阳极CO积炭能显著改善电池性能。Solid oxide direct carbon fuel cell （SO-DCFC） has attracted more and more attention due to its unique advantages in the clean coal utilization. This paper depicted the basic concept and features of SO-DCFC, and comprehensive analyses of its main three research aspects including anodic reaction mechanisms, mechanism modeling and simulation, and performance improvement were also presented. Further research and development indicate that： the reaction mechanism in the anode is closely related to the contact between the carbon fuel and the anode, which is of great importance in the performance enhancement; the carbon direct electrochemical reaction will not take place when the carbon and anode are just physical contact; the gasification between carbon and CO2 is the rate determine step of SO-DCFC performance; the mechanism modeling and simulation of SO-DCFC should be strengthened; the performance is significantly improved by introducing carbon catalytic gasification and inhabitation of anodic CO carbon deposition.
