摘要
本文采用多碘离子(I_3^-)作为阴极电子受体,实验比较了传统"H"型微生物燃料电池(MFC)和带交指型阴极流场的MFC(IMFC)的性能。结果表明,与"H"型MFC相比,IMFC在启动后具有较高的工作电压和最大功率密度。这主要是由于IMFC具有较小的电池内阻和较佳的传质特性所致。IMFC最大产电功率密度低浓度范围内随阴极电子受体的浓度的增加而增加,几乎不受阴极水力停留时间的影响。
The performance of the microbial fuel cell using an interdigitated flow field in cathode （IMFC） was compared with the conventional one （H-type）. The triiodide anion complex （I3-） was used as cathodic electron acceptor in this experiment. The results demonstrated that IMFC has a higher steady cell voltage after incubation and a larger maximal power density. This can be attributed to the lower internal resistance and the better mass transfer property of IMFC. In addition, it was found that the maximal power density of the IMFC increased with the increase of I3- concentration and showed no relationship with hydraulic retention time.
