Mitigating Voltage Reversal Effects in Stacked Fuel Cells: Strategies for Improvement

Abstract

Microbial fuel cells (MFCs) represent a promising avenue in the quest for sustainable energy solutions. However, the phenomenon of voltage reversal  significantly influences their operational longevity, particularly when subjected to fuel starvation at the anode during operation. This research investigates the critical role of voltage reversal in MFC performance, focusing on its impact during stacking and series connection of multiple cells. Through experimental analysis and theoretical modeling, this study elucidates how voltage reversal  affects voltage output, current generation, and overall efficiency of MFC arrays. Insights gleaned from this research are pivotal for optimizing MFC design and operation, enhancing their viability as renewable energy sources in the transition towards a cleaner energy future.
