摘要: 研究了三级液固厌氧流化床微生物燃料电池(MFC)串并联的产电性能。同时考察了活性炭装填高度、阳极面积等因素对燃料电池产电性能的影响。结果表明:将燃料电池串联时,总电压为1 500 mV,等于3个单级电池的电压之和,能够有效地提高燃料电池的输出电压,最大功率密度为028 W·m-2。而并联时,输出电压仅为450 mV左右,和单级电池输出电压大体相当,最大功率密度为0074 W·m-2。活性炭的装填高度增加1倍,电压升高了20%左右。阳极面积增加1倍,产电量增大了30%。

Abstract: The effects of the connection manner of fuel cells, the filling height of activated carbon and anode area on electricity generation performances were investigated in the liquidsolid anaerobic fluidized bed singlechamber membrane aircathode microbial fuel cells (MFCs). The results showed that, the voltage of three MFCs in series was about 1 500 mV, which was equal to the total of three single batteries and improved the output voltage of the MFC effectively. The maximum power density was 028 W·m-2. In parallel, the total voltage was only 450 mV which was the same as the single cell. And the maximum power density was 0074 W·m-2. The electricity generation increased by increasing the filling height of activated carbon. The voltage increased 30% when the area of anode doubled.
Key words: anaerobic fluidized bed; microbial fuel cell; parallel series; electricity generation performance
