Power management system for microbial fuel cell powered water quality monitoring system

摘要

The paper presents the design and test results of a power management system for a microbial fuel cell (MFC) powered water quality monitoring system, where sensors and communication devices are used to collect water quality data in a water body such as a river or a lake and transmit the data to a remote computer, and a MFC is used as the energy source for the sensors and communication devices. The power management system bridges the gap between the MFC and the water quality monitoring system by generating sufficient voltage and current for the sensors and communication devices using the low voltage and low current of the MFC.
