摘要

针对双室微生物燃料电池（dual chamber microbial fuel cell，DCMFC）中的水传输现象，研究了DCMFC中水传输现象产生的原因以及影响水传输量的各种因素。结果表明，在DCMFC中，阴阳极间水传输量随着放电电流的增大而增大；当阳极液为1500 mg·L-1化学需氧量（COD）培养基和50 mmol·L-1磷酸缓冲盐的混合溶液、阴极液为50 mmol·L-1 K3[Fe（CN）6]和50 mmol·L-1磷酸缓冲盐的混合溶液，电池电流为5 mA时，电池阴阳极间的水传输量为0.045 ml·h-1。此外，研究还表明，阴阳极间PBS溶液浓度差以及质子交换膜厚度对DCMFC的阴阳极间水传输量有着重要的影响。

Abstract

Various factors affecting the water transfer between the anode and cathode of a dual chamber microbial fuel cell (DCMFC) were studied. The results showed that the amount of water transfer increased with the increase of the discharging current; With 1500 mg·L-1 chemical oxygen demand(COD) and 50 mmol·L-1 phosphate buffered saline in the anode

50 mmol·L-1 K3[Fe(CN)6] and 50 mmol·L-1 phosphate buffered saline in the cathode

the amount of water transport between the anode and cathode is 0.045 ml·h-1 at a discharging current of 5 mA. In addition

the study demonstrated that the concentration difference of the PBS solution between the anode and the cathode

the thickness of the proton exchange membrane have an important influence on the amount of water transfer between the anode and the cathode in the DCMFC.
