摘要: 为了寻求可提高微生物燃料电池(MFC,Microbial Fuel Cell)产电性能的隔膜材料,对碱性电池隔膜纸、锂离子电池隔膜纸及两种不锈钢活性炭隔膜材料进行了系统的分析和比较.结果表明,碱性电池隔膜纸虽然有良好的质子透过性,但其水分渗透性和氧扩散较高,有待进一步的改进;辊压活性炭和涂刷活性炭隔膜的功率输出均优于目前MFC常用的阳离子交换膜,这是由于前两者的隔膜阻力小;而辊压活性炭和涂刷活性炭隔膜的特点接近,且涂刷活性炭隔膜的成本更低,是较为理想的MFC隔膜材料.

Abstract: In order to obtain a separator material with higher performance and lower cost, four materials including alkaline battery separator, lithium-ion battery separator, and two different kinds of activated carbon-stainless steel separators were discussed. The results show that, the ordinary alkaline battery separator has excellent permeability of hydrogen, but the high permeability of moisture and oxygen restrains its application in microbial fuel cell (MFC) and needs to be further improved. The output power of MFCs with the rolled and brushed activated carbon-stainless steel separators is higher than that with cation exchange membrane, due to the lower resistance. The characteristics of the rolled and brushed activated carbon-stainless steel separators are similar, while the cost of the latter is lower, thus the brushed activated carbon-stainless steel separator is considered to be the ideal separator material for MFC.
