直接碳燃料电池技术发展

DEVELOPMENT OF DIRECT CARBON FUEL CELLS TECHNOLOGY

直接碳燃料电池(DCFC)是碳燃料与空气发生电化学反应,将化学能直接转化为电能的发电装置,其能量转化效率高达80%以上。根据电解质的不同DCFC可分为熔融氢氧化物电解质DCFC、熔融碳酸盐电解质DCFC及固体氧化物电解质DCFC。论述了不同DCFC的工作原理及性能,分析了可能对DCFC性能产生影响的因素,同时介绍了目前具有代表性的DCFC结构及研究现状。

The direct carbon fuel cells（DCFC） are power generation devices which transform chemical energy into electric power directly in electro-chemical reaction between carbon fuel and air,the energy thransformation efficiency of DCFC can reach more than 80%.Based on different electrolytes,DCFC can be divided into molten hydrate DCFC,molten carbonate DCFC,and solid oxide DCFC etc..The working principle and performance of different DCFC have been expounded,and the factors which may affect the performance of DCFC being analysed,at the same time,some representative cell structure of DCFC and status quo of research being presented.
