Description

technical field [0001] The invention relates to a microbial fuel cell capable of real-time sampling based on ITO glass and a manufacturing method thereof. Background technique [0002] Microorganisms such as Shewanella putrefaciens and Escherichia coli produce electrons during their metabolism. If these electrons are collected and continuously exported, they are microbial fuel cells. A microbial fuel cell is a device that uses microorganisms as a catalyst to oxidize organic matter in wastewater and generate electricity. During this electricity generation process, microorganisms will decompose organic matter in water, including petroleum products, food residues, acids, antibiotics, etc., purify water quality and output electricity at the same time, so microbial fuel cells are an environmentally friendly energy source. [0003] The microbial fuel cell is mainly composed of two parts, the anode chamber and the cathode chamber. The microorganisms are placed in the anode chamber...

AI Technical Summary

Problems solved by technology

[0004] Traditionally, carbon paper, carbon felt, graphite, etc. are often used as anodes to conduct electrons. Some of these materials are soft, and some have to be divided before use, which is not conducive to the production of integrated microbial fuel cells.

At present, the research on microbial fuel cells is popular. The above electrode materials are all opaque materials, and it is impossible to observe the changes of microbial colony form from the bottom of the fuel cell. The process of making microbial fuel cells with soft materials and graphite materials is relatively complicated and time-consuming. Many, the anode of soft material is not conducive to the export of current

Therefore, the production cost of traditional microbial fuel cells is high and the production process is complicated.

[0005] In addition, traditional microbial fuel cells often adopt a closed design, which is not conducive to the real-time collection and research of microorganisms and their metabolites during battery operation, and is also not conducive to the replacement and replenishment of microorganisms.
