Pseudomonas-anode photosynthetic solar fuel cell system and preparation method and application thereof

Abstract

The invention discloses a pseudomonas-anode photosynthetic solar fuel cell system and a preparation method and application thereof. The fuel cell comprises an anode photosynthetic solar fuel cell, pseudomonas microorganisms and a resistor. The anode photosynthetic solar fuel cell is of a single-chamber structure and comprises soil, a water body, a green aquatic plant and two electrodes, wherein the root of the green aquatic plant penetrates through the water body and is arranged in the soil, one electrode is flatly laid in the soil to serve as an anode, the other electrode is flatly laid on the interface of the soil and the water body to serve as a cathode, the pseudomonas microorganisms are added to the root of the green aquatic plant, and the two ends of the resistor are connected with the anode and the cathode respectively. The fuel cell converts chemical energy contained in organic matters and inorganic matters into electric energy under the catalytic action of electrochemical active microorganisms and has the advantages of high energy conversion efficiency, mild reaction conditions, cleanness, no pollution and the like.

Description

technical field [0001] The invention relates to the field of plant-microbial fuel cells, in particular to a pseudomonas-anode photosynthetic solar fuel cell system and its preparation method and application. Background technique [0002] Microbial fuel cell is a new type of device that converts chemical energy in organic or inorganic substances directly into electrical energy by using microorganisms as catalysts. The basic principle is: microorganisms in the anode area generate electrons through substrate metabolic activities, and electrons pass from the anode through wires and external resistance. [0003] Electricity generation and pollutant degradation are two basic functions of microbial fuel cells (MFCs), and they are also the most attractive advantages of microbial fuel cells (MFCs) as a new type of environmental governance and energy technology. A large number of studies have shown that: compared with general anaerobic biodegradation technology, microbial fuel cells ...

AI Technical Summary

Problems solved by technology

[0011] The environmental remediation function of the anode photosynthetic solar fuel cell (APSFCs) system is mostly focused on wastewater treatment, and single strains such as electrochemically active microorganisms and characteristic pollutant-degrading bacteria are often used to inoculate. Although good degradation and electricity production efficiency have been achieved, However, its application in the real environment is less likely

In the natural environment, the inactivation rate of a single strain is high and the operability is low
