    Abstract: The present invention provides a microbial fuel cell power system based on a microbe-based fuel cell such as a benthic microbial fuel cell (BMFCs). In accordance with the present invention, one or more BMFCs can be connected to one or more batteries such as a nickel metal hybrid (NiMH) or sealed lead acid (SLA) battery and can be used to charge the batteries for long-term persistent underwater use. At any time, some of the connected batteries are being charged by the BMFC, while the others are being used to power a connected device. By using electrically isolated fuel cell converters, the batteries can be charged while in circuit. With non-isolated converters, pairs of batteries can be switched between offline charging and online discharging. The battery system can be controlled by a control system that comprises a microcontroller that periodically measures system voltages and currents, swaps the batteries being charged, and records the system results for post-mission analysis. The batteries can be connected to an underwater monitoring system such as the Acoustic Doppler Current Profiler (ADCP) or Shallow-Water Environmental Profiler in Trawl-Safe Real-Time Configuration (SEPTR) systems used by the U.S. Navy and can provide long-term persistent power supplies to such systems.

    Abstract translation: 本发明提供了一种基于微生物燃料电池的微生物燃料电池动力系统,其包括底栖微生物燃料电池(BMFC)。 根据本发明,一个或多个BMFC可以连接到一个或多个电池,例如镍金属混合(NiMH)或密封铅酸(SLA)电池,并且可以用于为长期持续的水下电池充电 使用。 在任何时候,一些连接的电池正在由BMFC充电,而其他电池正在用于为连接的设备供电。 通过使用电隔离的燃料电池转换器,电池可以在电路中充电。 使用非隔离转换器,可以在离线充电和在线放电之间切换成对电池。 电池系统可以由包括周期性地测量系统电压和电流的微控制器的控制系统控制,交换正在充电的电池,并记录用于后任务分析的系统结果。 电池可以连接到水下监控系统,如美国海军使用的拖网安全实时配置(SEPTR)系统中的声学多普勒电流分析仪(ADCP)或浅水环境分析仪,并可提供长期持续的 这种系统的电源。
