Investigation on the Treatment of Marine Oily Wastewater Using Stacked Microbial Fuel Cell Configurations

Abstract

In the process of microbial fuel cell (MFC) scale-up, the collection of clean energy is an important part of the application. However, due to the limitations of the structure and performance of the MFC itself, the power generation capacity of the device is weak and the output voltage is low, so it is difficult to achieve commercial application of microbial fuel cell technology. In order to obtain a higher voltage output capacity and further study the performance characteristics of amplified MFC, this paper uses the existing equipment in the laboratory to construct two stack schemes of double MFC and three MFC through the stacking design of single cells, and explores the effects of different modes on the power production performance and oil degradation performance of series MFC devices. The advantage of this design is that the MFC structure is simplified, making the device more compact, and saving investment space for industrial applications. The battery series technology is used to expand the power production performance of the device and improve the efficiency of energy recovery.

Key findings

• ▸The stacked MFC configurations can achieve higher voltage output capacity
• ▸The series MFC devices show improved power production performance
• ▸The stacked design enhances oil degradation performance
