Development of a System Based on a Microbial Fuel Cell for Coastal Monitoring of Marine Areas

Abstract

Hydrological monitoring is necessary for successful aquaculture management. In this article, the technology of micro-fuel cells for powering hydrological monitoring sensors is tested. The device operated at a depth of two meters on the territory of the Zapad biostation of the A.V. Zhirmunsky National Scientific Center of Marine Biology Far Eastern Branch of the Russian Academy of Sciences in the Quiet Backwater Bay of the Vostok Bay, Peter the Great Bay. The total capacity of the manufactured MFC was 1.7 mW. It took 46 MJ to send the signal. The frequency of sending was 6 times per minute in laboratory conditions and in the range from 2 to 4 minutes in field conditions. The power consumption of the entire system was 276 mW. The LoRA protocol was used to transmit the signal. The transmission distance was 950 meters
