摘要

Microbial fuel cells (MFCs) generate electricity from organic substrates by breaking them into simpler compounds. While primarily acetate is considered as substrate due to its highest coulombic efficiency, other complex organic substrates needs to be utilized to improve the practicality of MFCs. However, as the coulombic efficiency of other substrates is low, addition of mediators improves the cell performance. In this study, Ping – Pong mechanism is considered to optimize the performance of the MFCs. The effect of substrate and mediator concentration on the operating parameters and cell output is modeled. The model is validated with the experimental data taken from the literature and found to compare well.
