Abstract: |
Underwater bioelectricity system is a kind of in-situ power generation device placed at the interface of natural water body/sediment, which can be used to drive low-energy power equipment in remote waters such as deep sea and far sea. The work aims to solve the problems in the current underwater bioelectricity systems such as poor power collection efficiency and limitedpower supply capacity. The BMFC based on a carbon felt array anode and the PMS featuring a two-stage charge pump compound boost structure were developed. The two subunits were coupled to construct a prototype of the underwater bioelectricity system, and its power supply capability was evaluated. The test results demonstrated that the PMS effectively captured 13~18 mW continuous input power from the BMFC and stored it in the medium, achieving a power collection efficiency of 60.65%. The power generated by the BMFC was sufficient for powering temperature / pH sensors and underwater communication, while also yielding a net power gain of 385.68 J per day. The underwater bioelectricity system developed in this study enables efficient collection and storage of underwater bioelectric power, providing a long-term and stable in-situ power supply for marine environmental information collection and transmission systems. |
