Owing to the virtues of high efficiency, green and sustainability, microalgae photobioreactor (PBR) is coupled with microbial fuel cell (MFC) achieve CO2 fixation electricity/bioenergy collection. In this paper, a novel self-breathing oxygen-consuming carbon felt (SOC) firstly proposed. It subsequently integrated into PBR-MFC optimize O2 concentration distribution separate microalgae/bacteria. The results show that solution environment (pH, dissolved oxygen internal resistance) coupling system are significantly regulated by SOC. pH electrolyte in cathode increased 2.9% 6.1%, respectively, compared without anode, system’s Rohm RCT dramatically decreased 64.6%, 59.2% 19.0%, respectively. Compared PBR-MFC, PBR-MFC-SOC-1 has efficiency 26.7% power density 474 mW·m-2, improving 21.85% 38.81%, integration SOC credited improvement performance. transition from “disordered” “orderly” porous ion transport channel eradication antagonism between microorganisms two key aspects its favorable benefits.
