Abstract
Microbial fuel cell (MFC) has attracted a great attention in the recent years due to its advantage of simultaneous energy generation and pollution removal. However, utilization of MFC technologies a challenging issue because of the low energy output and high expenses. Generally, using ion exchange membrane in MFC contributes to a large proportion of the construction costs. Without using a membrane, oxygen intrudes to the anode chamber which will inhibit the anode reaction and decreases the coulombic efficiency. As a solution, using less expensive membranes can facilitate the commercialization of MFC technology.

Abstract
Choosing the appropriate ion exchange membrane in vanadium redox flow batteries plays an important role in achieving optimal system performance. In this article, the implementation of commercial cation exchange membranes (Nafion 115, Nafion 117, and Nafion 212), anion exchange membranes (FAP 450 and QA-PFE), and the combination of them are investigated. In this regard, the effects of membrane type, thickness, electrical conductivity, and the transfer of vanadium species at different current densities are examined carefully. In addition, the influences of the flow rate and the concentration of electrolytes are investigated using a comprehensive developed model. The model predictions are...
