Optimizing methane production from CO2 through microbial electrosynthesis: A study of ion exchange membranes and cathodic potential parameters
The present study aims to compare the performance of MES reactors utilizing CEM and AEM under varying applied voltage conditions (cathodic potentials ranging from -1.0 to -1.2 V vs. Ag/AgCl). Key performance metrics, including current production, methane yield, and coulombic efficiency, were evaluated alongside ion transport mechanisms and microbial community structures.
