Abstract

The invention provides a microbiological fuel cell composite material anode and a manufacturing method thereof, and relates to a fuel cell composite material anode and a manufacturing method thereof, so that the problems of low electricity generation capacity and low removal rate of organic pollutant in water body or deposit can be solved. The anode is a compressing piece, the anode comprises a first wire mesh layer, a first non-metal sheet layer, a second wire mesh layer, a second non-metal sheet layer and a third wire mesh layer, the second non-metal sheet layer is positioned between the first wire mesh layer and the second wire mesh layer, the second non-metal sheet layer is arranged between the second wire mesh layer and the third wire mesh layer. The main steps for manufacturing the microbiological fuel cell composite material anode comprise: 1) irregularly etching the wire mesh, 2) performing a nitrocementation to liquid phase plasma, 3) compacting the material, 4) performing a carburization to liquid phase plasma, and 5) treating the composite material. The invention is used for power generation of the microbiological fuel cell and the organic pollutant in water body deposit removal.

Description

technical field [0001] The invention relates to a fuel cell composite anode and a manufacturing method thereof. Background technique [0002] At present, many countries in the world are facing serious problems of environmental pollution and energy crisis. With the research and development of global new energy and sustainable energy, research on microbial fuel cells (MFC), especially microbial fuel cells The research and manufacture of anodes and cathodes has become one of the important ways to solve the two major problems of the environment and energy crisis in the world today. As a dual-function MFC technology for treating pollutants and generating electricity, it has attracted widespread attention from various countries. The electricity generation efficiency of microbial fuel cells and the removal rate of organic pollutants are the two major indicators in this field. Most of the research at home and abroad is in the scientific research or experimental stage. No real break...
