Temperature-controlled microbial fuel cell

Abstract

The invention discloses a temperature-controlled microbial fuel cell which comprises a cell body and an ion exchange membrane, wherein the ion exchange membrane is arranged in the middle of the cell body and divides the cell body into an anode chamber and a cathode chamber; an anode body is arranged in the anode chamber; a cathode body is arranged in the cathode chamber, and an opening is formed in the upper end of the cathode chamber; the anode body is inoculated with anaerobic microorganisms; the cathode body is inoculated with aerobic microorganisms or is not inoculated with microorganisms; the anode body is connected with the cathode body through an external resistance to form a closed loop; both the anode body and the cathode body are connected with a temperature control system; the temperature control system comprises a direct current power supply, a temperature controller and a temperature sensor. According to the invention, the surface temperatures of the anode body and the cathode body of the microbial fuel cell can be quickly regulated and controlled, so that the biological activities of the microorganisms are improved, and the reduction reaction of an electron acceptor on the cathode body is accelerated, therefore, the performance of the microbial fuel cell is improved; the temperature-controlled microbial fuel cell is simple in structure and convenient for the expansion of chemical industry production and application.

Description

technical field [0001] The invention relates to a battery, in particular to a temperature-controlled microbial fuel cell, which belongs to the technical field of green bio-energy. Background technique [0002] Microbial Fuel Cell (MFC) consists of an anode chamber and a cathode chamber, which are separated by an ion exchange membrane. Anode microorganisms degrade organic matter in an anaerobic environment to produce electrons, protons and carbon dioxide; electrons are transported to the anode and reach the biocathode through an external circuit load, and protons pass through the ion exchange membrane from the anode chamber to the cathode chamber; the electron acceptor oxygen in the cathode chamber obtains electrons at the cathode and protons are reduced to water, thereby generating an electric current. Microbial fuel cell is a green new energy technology, which has been extensively and deeply studied in recent years, and provides a new way to solve energy shortage and sewag...
