Evaluation of Scale-Up And Environmental Factors On Microbial Fuel Cell

Abstract

Considering the recent world situation of the electricity for mankind and also energy requirements have been increasing exponentially worldwide. People is facing on their energy challenge and most countries in the world are on their way searching for new renewable energy resources technologies which consider for environment protection. An estimated 1.3 billon people - 17.3% of the global population - did not have access to electricity services for their daily lives, especially at night. Various studies on alternative renewable energy generation are becoming more and more priority, because humanity's increasing concern for electricity needs and climate change is happening. One potential way to continue to be explored as a solution to solve this problem is the over-reliance on electricity based on fossil fuels. Then the microbial fuel cell (MFC) is an opportunity challenge that is very interesting for further development. There are still many open opportunities to find out the effect of increasing volume and environmental factors on MFC operations. The results showed that the maximum value for mixed samples was 12720 ± 114.31 mV / m², 9830 ± 81.79 mV / m² and 1650 ± 65.32 mV / m² for mixed samples of persimmon and soil waste, leaf molds and rice bran respectively -one; the electromotive force of the sample mixture of persimmon and soil waste is around 22 ± 0.01 V / m². In addition, the power density correlates with an increase in the MFC scale which reaches 2109.9 mW / m², 2319.88 mW / m², 4384.06 mW / m² and 10317.19 mW / m² for 100 cm², 150 cm², 300 respectively. cm2 and 500 cm² respectively. And the voltage generator works well even on a number of environmental factors (especially pH and humidity). In summary, this study shows and agrees that voltage generation can be maintained to increase during reactor increases and MFC by using organic waste (especially using persimmon fruit waste) can be operated under any environmental conditions.
