Cylindrical microbiological fuel cell

Abstract

The invention discloses a cylindrical microbiological fuel cell. The cylindrical microbiological fuel cell consists of an anode chamber, a cathode chamber, a proton membrane assembly, silica gel gaskets, a fastening bolt and a base, wherein both the anode chamber and the cathode chamber have an end sealing cylinder structure and are provided with electrode jacks, sampling holes and exhausting holes; anode carbon paper and cathode carbon paper are arranged inside the anode chamber and the cathode chamber and are hermetically led out from the electrode jacks through wires respectively; the surface of the cathode carbon paper is plated with platinum catalysts; air inlet holes are formed at the bottoms of the anode chamber and the cathode chamber; the proton membrane assembly comprises a proton membrane, two base plates and two silica gel gaskets; the proton membrane is square; square holes are formed in the centers of the silica gel gaskets and the base plates; and the assembled fuel cell is fixed by bolt holes on the circumference of a cylindrical wall. The cylindrical microbiological fuel cell has the advantages of small resistance and high power as the cell body is cylindrical and the anode and cathode chambers are close, good air tightness due to the silica gel gaskets arranged between the proton membrane and a clapboard, improvement on the coulomb effect of the cell as the oxygen in the cathode does not diffuse to the anode, compact structure and low cost.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a cylindrical microbial fuel cell. Background technique [0002] In recent years, with the rapid development of the global economy, the rapid advancement of modern industrialization, the increasing shortage of energy, and the increasingly obvious contradictions of environmental degradation, water pollution has become a major problem restricting the sustainable development of the economy, but most of the existing water treatment technologies It requires high operation and management costs and consumes a lot of power. Microbial fuel cell (MFC) can not only effectively treat waste water but also generate electricity, which solves the two major problems of comprehensive utilization of energy and environmental pollution, and has become one of the most popular research topics in the field of environment. [0003] A microbial fuel cell (MFC) is a device that uses microor...
