Abstract

The invention discloses a submarine low-power power supply system with a unit body structure. The submarine low-power power supply system comprises a plurality of microbial fuel cells and a fuel cell stack, wherein a whole pole plate structure is adopted by cathodes and anodes of the microbial fuel cells; a resistor and an electric wire are solidified in a pole plate; the fuel cell stack is formed by series connection, parallel connection or parallel-series connection of the microbial fuel cells; the anodes arranged at the lower parts of the unit body microbial fuel cells and the cathodes are arranged at the upper parts of the unit body microbial fuel cells; the anodes are arranged in an anaerobic sediment; and the cathodes are arranged in a liquid environment containing dissolved oxygen. The submarine low-power power supply system is good in invisibility, stable in output, fast in power supply response, long in running time, high in reliability and high in maneuverability, meets the special requirements of modern warfare put on an energy device, and has a wide application prospect in the field of military and a marine geological environment.

Description

technical field [0001] The invention belongs to the field of submarine power supply energy, in particular, the invention relates to a unit structure submarine low-power power supply system. Background technique [0002] Microbial Fuel Cell (MFC) is a device that uses microorganisms as a catalyst to directly convert the chemical energy contained in organic matter into electrical energy. Seabed sediments store a large amount of energy in the form of organic carbon, the content of organic carbon is generally 2%, if it is completely oxidized, each liter of sediment can produce 6.1×10 4 The energy of J (17Wh / L) provides a material basis for the development of MFC. Subsea microbial fuel cells use sediment as a remote power source to supply power in situ on the seabed, serving monitoring and detection equipment for subsea operations. The anode is placed in the anaerobic sediment, and the cathode is placed in an environment where the overlying water contains dissolved oxygen. The ...
