- Abstract
- This study reports the development of a co-laminar
flow microbial fuel cell (MFC) with single-walled carbon nanotube
(SWCNT) electrodes microfabricated by electrophoretic deposition. The effects of the flow channel height and the shear stress at
the anode biofilm on the power density and the fuel utilization rate
of the co-laminar flow MFC were investigated to improve the
MFC’s performance. The power density and the current density
increase with increasing channel height, while the flow rate is kept
constant. Meanwhile, when the flow rate was also adjusted
according to the channel height to yield the optimum shear stress
for biofilm formation, the performance improved further, but fuel
utilization decreased. The maximum measured power density (143
± 1 μW cm−2
) of the developed MFC is better than those of
microfabricated metal-based electrode MFCs. This micromachined, carbon-based, flow-over electrode improves the MFC’s performance and enables mass production of MFCs integrated
with planar microdevices based on the microelectromechanical system process.
