The main structure of the anode electrode is a porous hard conductive fiber block, and moderate thermoacidophilic iron-oxidizing bacteria and a yeast extract agar composite nutrient mediumadapted to the moderate thermoacidophilic iron-oxidizing bacteria are implanted into the anode electrode. The device is relatively simple in structure, environmentally friendly, reliable and environmentally friendly, and power is generated through movement assisting microorganisms.

Description

technical field [0001] The invention relates to the technical field of electrical devices, in particular to a motion-assisted thermophilic anaerobic single-chamber microbial power generation device and a manufacturing method thereof. Background technique [0002] Microbial fuel cell is a new type of bioreactor, a device developed on the basis of electrochemical technology that uses microorganisms as a catalyst to convert chemical energy stored in organic matter into electrical energy. In addition to the advantages of general fuel cells such as high efficiency and no pollution, microbial fuel cells also have a wide range of fuel sources (renewable organic substances such as glucose and starch that exist in large quantities in nature can be used as fuels), and mild reaction conditions (can be used at room temperature and pressure) and react under neutral conditions) and other characteristics. Factors affecting the power generation performance of microbial fuel cells mainly in...
