This paper reports the design, fabrication, and testing of a microliter scale Microbial Fuel Cell (mu mu MFC) based on silicon MEMS fabrication technology. mu MFC systems are operated under different loads or open circuit to compare the effect of different acclimatization conditions on start-up time. Shewanella oneidensis MR-1 is preferred to be the biocatalyst. The internal resistance is calculated as 20 k Omega under these conditions. Acclimatization of mu MFC under a finite load resulted in shorter start-up time (30 hours) when compared to the open load case. Power and current densities normalized to anode area are 2 mu W/cm(2) and 12 mu A/cm(2) respectively. When the load resistance value is closer to the internal resistance of the mu MFC, higher power and current densities are achieved as expected, and it resulted in a shorter start-up time. Further studies focusing on the different acclimatization techniques for mu MFC could pave the way to use mu MFCs as fast and efficient portable power sources.
