Stackable single cell microbe fuel battery

Abstract

The invention discloses a pile type single room microbiological fuel cell; the battery is the sheet style structure, battery thickness is 5-30 centimeter, two groups of membrane electrodes altogether used an anode chamber, which is advantageous for composing the large-scale microbiological fuel cell heap, in order to output a greater voltage and electric current to satisfy the different current collector demand. The monomer battery uses the air type negative pole, does not need aeration, simultaneously does not need to add vector to the negative pole room, can greatly reduces the movement cost, and avoids the environmental pollution which creates by adding vector. In the anode chamber increases the carbon fiber to enhance the anode relative surface product, may enhance the monomer battery current density 3-10 times. The battery movement uses the method of upside feed-water, the base high and dry, reduced the backflow equipment demand, but also can save 50% -70% of the electrical energy. The invention is a clean advanced energy technology; and it has the broad application prospect in the municipal, industry, agricultural and spatial organic waste water processing.

Description

technical field [0001] The invention relates to a stackable single-chamber microbial fuel cell, which is convenient to be stacked into a large-scale microbial fuel cell stack to meet the requirements of electrical equipment with different powers. The invention belongs to the field of energy and environment technology, which is used for organic wastewater purification and energy recovery, and has broad application prospects in the treatment and resource utilization of municipal, industrial, agricultural and space organic wastewater. Background technique [0002] Microbial fuel cells (MFCs) are devices that use the enzymes of anaerobic microorganisms to convert chemical energy stored in organic matter into electrical energy. The fuel for its power generation can be organic wastewater, the cost of power generation is very low, and it can purify sewage while generating electricity, so it is a sustainable and clean advanced energy technology with broad application prospects.

Problems solved by technology

Existing microbial fuel cell stack cells adopt a double-chamber structure design, which has many disadvantages: the single cell is thick, so the space occupied by the cell stack is large, and it is difficult to stack into a large-scale cell stack; the single cell of the double-chamber structure The power output of the battery is lower than that of a single-chamber battery; and the cathode needs to add ferricyanide as a mediator, which not only increases the operating cost of the battery, but also causes secondary pollution to the environment due to the toxic mediator

The electricity consumed by these devices cancels out the electricity generated by MFCs, making MFCs no clear competitive advantage over other wastewater treatment or power generation devices
