Double-chamber microfiltration membrane multi-anode microalgae biofuel cell

Abstract

The invention relates to a double-chamber micro-filtration membrane multi-anode microalgae bio-fuel cell, belonging to the technical field of a microbial fuel cell. An anode plate adopts a mode of multiple stacked pole plates to expand the microalgae absorption area, and seawater enriched with chlorella can be directly injected to the anode plate; a cathode plate is loaded with a Co-C-N oxygen reduction catalyst to form an air cathode; during the running of a device, the seawater solution vaccinated with algae seeds is introduced to a photobioreactor so that the algae seeds breed and grow through photosynthesis, illumination cultivation is carried out on the photobioreactor, the seawater solution enriched with the microalgae is taken as an anode solution to be injected to an anode chamber, meanwhile, the seawater is permeated into a negative electrode to form a cathode solution, the reactor can output 0.2V open-circuit voltage, and the conversion from light energy to biomass energy and then to electric energy is achieved. In the reactor, a noble metal catalyst and a proton exchange membrane are not used, an anaerobic environment is not needed to be maintained during the running process, an organic carbon source is not needed to add, the reactor is simple to operate, is low in cost and stable in performance, and can be used for continuous and high-efficiency microalgae power generation process.

Description

technical field

[0001] The invention relates to a double-chamber microfiltration membrane multi-anode microalgae biological fuel cell, which belongs to the technical field of microbial fuel cells. Background technique

[0002] Biomass energy is a renewable energy source and the only renewable carbon source, which is expected to become a substitute for petrochemical resources. Among the many biomass energy sources, microalgae is called the third generation of bioenergy, which has the advantages of short cycle, high yield, stable properties, and strong environmental adaptability. Microalgae use light energy and CO 2 Synthetic organic matter is an excellent biological carrier that takes into account both carbon sequestration and solar energy storage. Using microalgae energy, while generating huge energy, it can also consume carbon dioxide and solve climate problems. Therefore, microalgae energy is considered to be a promising energy source, and the industrialization of micro...

Embodiment 1

[0036] Double-chamber microfiltration membrane multi-anode microalgae biofuel cell, including: anode plate 1, anode fixing frame 2, anode chamber 3, diaphragm 4, cathode chamber 5, cathode plate 6 and cathode fixing plate 7;

[0037] The diaphragm 4 separates the anode chamber 3 and the cathode chamber 5; the anode chamber 3 is a square pool with the top removed, and a through hole is opened on one side wall of the pool; the anode holder 2 fixed with the anode plate 1 is inserted into the anode Chamber 3, the packaging of the top of the anode chamber 3 can be realized; a sheet with a through hole in the middle and a liquid injection channel on the top is inserted between the cathode plate 6 and the diaphragm 4 as the cathode chamber 5, and the cathode plate 6 passes through the cathode fixing plate 7 is fixed; a through hole is opened in the middle of the cathode fixing plate 7;

[0038] The diaphragm 4 is a slow qualitative filter paper or a microfiltration membrane;

Embodiment 2

[0053] Using Chlorella common seawater as the working algae species, a double-chamber multi-anode microalgae biofuel cell reactor was assembled using a proton exchange membrane instead of microporous filter paper. The test process was the same as in Example 1, and the measurement results were as follows: Figure 4 shown. The maximum output power of a single reactor is 29μW. By comparing with Example 1, it can be seen that the practical application effect of the double-chamber microfiltration membrane multi-anode microalgae biofuel cell proposed by the present invention is better.
