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.
