CARBON NANOPARTICLES ON GRAPHITE ANODE FOR MICROBIAL FUEL CELL

[Category : - RENEWABLE ENERGY]
[Viewed 1687 times]

Novel carbon nanostructures are now being used in numerous potential applications namely nanomechanical devices, nanocomposites with unique properties, nanoconductors, field display, storage of natural gas and hydrogen . This brings up development of different methods for synthesising carbon nanomaterials. The widely used methods are arc discharges, pulsed laser vaporization and chemical vapor deposition. These synthesis techniques generally require the introduction of catalyst to influence growth and morphology of generated nanostructures.

Although different methods for synthesising carbon nanostructures are available, research is still going on for finding the cheap and easy method for commercial preparation of different carbon nanostructures with controlled morphology and high purity. The carbon soot obtained from burning of vegetable oils and animal based oils by using traditional method is found to contain carbon nanostructures including single-walled carbon nanotubes, multi- walled carbon nanotubes and carbon nanofibers.

The microbial fuel cell provides an altenative energy source. It uses microorganisms for current production from biologically mediated oxidation and reduction reaction. So, to harness electricity, electron transfer to the electrode is required. The attachment of biomass to electrode is, thus, essential for transfer of electrons. The higher surface area increases the attachment of biomass to the electrode. The carbon nanoparticles help in achieving the increase in surface area. SUMMARY OF THE INVENTION

The object of the present invention is to provide carbon nanoparticles synthesis by flame deposition on graphite anode for microbial fuel cell.

Fuel cell technology promises alternative energy source. The carbon nanoparticles which have high surface to volume ratio can be used to increase the power generation of the microbial fuel cell. The carbon nanoparticles are deposited on the surface of graphite anode by flame deposition method.

The increase in surface area enhances the biomass attachment and thus helps in increase of power production. Thus, carbon nanoparticles synthesised from flame deposition can be used to improve the anodic properties of microbial fuel cell.
