Electricity generation of a laminar-flow microbial fuel cell without any additional power supply.

ABSTRACT: Laminar-flow microbial fuel cells (LFMFCs) utilize the co-laminar flow feature in the microchannel as a virtual barrier to separate the anolyte and catholyte. However, for LFMFCs reported before, syringe pumps were always used to drive the fluid and form the co-laminar flow of anolyte and catholyte in the microchannel, reducing the net power output and the efficiency of the whole system. In this study, a laminar-flow microbial fuel cell (LFMFC) without any additional power supply is proposed. The LFMFC is successfully started-up after inoculation for 90 h. The anode biofilm distribution becomes sparser along the flow direction due to the thicker boundary layer and unfavorable crossover from the catholyte downstream. Moreover, the LFMFC delivers a maximum volumetric power density of 3200 W
