Abstract

Microbial fuel cell technology has a very broad development prospect in the field of marine emergency power supply, focusing on the impact of environmental factors of electron transfer of microbial fuel cell on the output voltage. Based on the BBD response surface method, the individual and interaction of environmental factors of electron transfer such as anode area, inoculation amount, GO/PANI content were investigated, and the mathematical model of output voltage was established. The results showed that the order of significance of the influencing factors was anode area > GO/PANI content > inoculation amount. In addition, there was a certain interaction among the three influencing factors, but the interaction was not significant, and the regression of the mathematical model was good. When the anode area is 4.55 cm², the inoculation amount is 3.13% and the GO/PANI content is 0.21 mg/mL, the predicted output voltage of the microbial fuel cell reaches 822.695 mV. Four parallel experiments were used for verification. The average output voltage of the microbial fuel cell is 821.725 mV, the relative standard deviation is as low as 0.12%, indicating that the model is more accurate and reliable in optimizing the environmental conditions of MFC electron transmission and predicting the output voltage.
