摘　　要：研究了以活性炭纤维(ACF)为燃料的熔融碳酸盐流化床电极燃料电池的极化规律,在温度为650℃、氮气、氧气及CO2流量分别为275 ml/min、10 ml/min和20 ml/min时,半电池的极化性能最好。在此工况下,以ACF为燃料的极化性能比以自制活性炭(橡木锯屑活性炭和竹质活性炭)为燃料稍差,原因是自制活性炭的体积电阻率较小,含氧官能团较多。Polarization characteristics of fluidized bed dectrode fuel cell anode using activated carbon fiber （ACF） as fuel were studied. The polarization performance of half cell was best when the temperature was 650℃, the flow of nitrogen, oxygen and CO2 was 275 ml/min, 10 ml/min and 20 ml/min, respectively. Under this working condition, the polarization performance using ACF as fuel was slightly worse compared with using self-made activated carbon （activated carbon based on bamboo and oak wood）. The reason was the volume resistivity of the self-made activated carbon was smaller, the surface oxygen functional groups were more.
