| 摘 要： | 海底沉积物生物燃料电池(简称海底生物燃料电池)是一种新型的海洋能源材料电池,它的发电机理主要是利用海底沉积层内细菌代谢产生电子,通过人工放置的改性阳极收集电子,产生电能,可用于驱动水下监测仪器的长期连续运行.本研究首先设计海底生物燃料电池实验室装置,利用电池串联升压的方式,实现其驱动小型电子装置和监测仪器的连续运行.在此基础上,设计并安装了实际海况电池实验装置,利用并联设计和特殊升压装置,在胶州湾浅海成功驱动小型电子装置的运行.本研究初步验证了海底生物燃料电池作为电源驱动仪器的可行性.

| Abstract: | Marine sediment microbial fuel cell(or Microbial fuel cell on ocean floor) is a kind of novel energy material.Its mechanism is that bacteria in the sediment produce electrons and transfer to a modified graphite anode that is connected with a cathode by external circuit,and the cathode is positioned in the water to consume these electrons by oxygen reduction,and electronic energy can be artificially obtained to drive small electronic vehicles on ocean floor to work continuously.Two cell structures in the lab are designed to get power,and these cells can be connected in series to increase output voltage and drive small electronic equipments(for example,radio,watch,and wireless temperature and depth sensor) for a long time.On the basis of that,another cell structure is further designed for a field test in JiaoZou Bay,Qingdao.Three cell structures are connected in parallel to increase output current,and a special voltage conditioner is designed to increase their cell output voltage,and finally,small electronic equipments are successfully driven for long-lasting time in the field.The research in the paper demonstrated the application feasibility that the microbial fuel cell on the ocean floor can be used to be a power supply for small monitor instruments or vehicles on the marine sediment in the future. |
