Benthic microbial fuel cells (BMFCs) are important energy-harvesting devices for underwater sensors and electronic devices. However, it is a challenging problem to ensure the robustness of BMFCs in harsh ocean environment. In particular, the anode buried in sediment is subject to burrowing organisms tunneling, which breaks the anaerobic condition, and the electrons generated by the anode will be consumed...
Microbial fuel cells (MFCs) are promising renewable energy sources for long-term underwater systems. The critical limitations of MFCs include low output voltage and bioturbation interference. A multianode MFC was proposed in our previous work to tolerate bioturbation problems. Due to the unique structure of the multi-anode MFC, an anode decoupling function is needed for power management. Conventional...
This paper presents the design of a new underwater energy harvesting system, which would provide persistent and sustainable power supply for remote underwater sensing and surveillance devices. The system consists of a marine sediment microbial fuel cell (MFC) and the associated power management system. The MFC exploits bacterial metabolic activities associated with the redox reaction to generate electrical...
