Abstract

The invention discloses a cloth cathode assembly for a microbiological fuel cell and a preparation method thereof. The cloth cathode assembly comprises a waterproof ventilation layer, a cloth base material layer and a conductive catalyst layer or comprises waterproof ventilation cloth and a conductive catalyst layer. The cloth cathode assembly adopts a low-cost non-membrane material to replace the traditional membrane material and adopts a high-stability conductive coating layer to replace an expensive cathode conductive material as a catalyst carrier and a current collector. Compared with the traditional membrane cathode, the cost of the cloth cathode assembly is reduced about 5 times to 20 times, and the cloth cathode assembly has a simple preparation process, does not needs a heat press device, can be cut or bent at will, can be used for MFC reactors with various types, such as a tube type, a square type, and the like, and is convenient to assemble.

Description

technical field

[0001] The invention belongs to the technical field of environment and new energy, and in particular relates to a cloth cathode assembly for microbial fuel cells and a preparation method thereof. Background technique

[0002] Microbial fuel cell (MFC) is a power generation device that directly converts chemical energy in organic matter into electrical energy, and has dual functions of power generation and organic waste disposal. MFC has a wide range of fuels. Domestic sewage, high-concentration organic wastewater, human and animal manure, etc. can be used as fuel for MFC. It can effectively remove organic matter while generating electricity. Therefore, it is an advanced biomass energy utilization technology with great development potential. It is expected to become a pillar technology for future organic waste treatment.

[0003] The basic principle of MFC is: organic matter is oxidized by microorganisms in the anaerobic anode chamber as fuel, and the electro...
