摘要
目的 改善目前水下生物供电系统能量收集效率低、供电能力弱的问题,方法 构建基于碳毡阵列阳极的水下生物电池单元,以及具有 2 级电荷泵复合升压结构的电源管理单元.将 2 个子单元耦合,构建水下生物供电系统样机,并对其供电能力进行评价.结果 测试结果表明,电源管理单元能够将生物电池13～18 mW 的持续输入能量有效收集至储存介质中,能量收集效率达到 60.65%.生物电池单元产生的能量在满足温度/pH传感器以及水下通讯机工作的同时,每天仍能够产生 385.68 J的净能量收益.结论 构建的水下生物供电系统能够实现水下生物电能的高效收集与存储,可为海洋环境信息采集与传输系统提供长期、稳定的原位能源供应.
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 limited power 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 bio-electricity system,and its power supply capability was evaluated.The test results demonstrated that the PMS effectively cap-tured 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 communi-cation,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.
