4.3 Effects of temperature on voltage generation
Figure 4 illustrates the effects of temperature on the voltage generation in the laboratory experiment. It was seen that when the temperature was 250 C then the amount of voltage was also higher compared to 50 C. The average winter and spring temperature in the Yamaguchi bay is around 50 C and 250 C, respectively and for this reason we fixed those temperature during the laboratory experiment. The bacterial activities increased in the increased temperature and consequently increased the voltage generation. At the 250 C, the peak voltage reached around 85 mV and at the 50 C the peak voltage reached around 48 mV. This proved that the temperature is one of the biggest affecting factors for the voltage output in the SMFCs. Lovley 2006 showed that the temperature is also a affecting factor for the waste water MFCs. The possible shortcomings of this particular research could be the effect of temperature in the field. The lower winter temperature could affect the power generation and consequently it could be affect the power supply to the sensors in the field. To minimize this problem, SMFCs could be developed and connec in a series connection and set in the tidal flat area.
