  • 2. ►Fuel cell is a device that converts a fuel directly into electricity in an electrochemical reaction.
  • 3. ► Fuel cell consists of an electrolyte layer in contact with an anode and a cathode on either side. ►The existing electrodes anode and cathode are porous are made up of compressed carbon.
  • 4. ►Hydrogen is fed to the anode where a catalyst seperates hydrogen’s negatively charged electrons. 2H2→ 4H+ + 4e- ►At the cathode , air is fed. so oxygen is combined with electrons. O2 + 4H+ + 4e- → 2H2O ►At this time the electric current flows in opposite direction. ►Net reaction: 2H2 + O2 → 2H2O
  • 5. ►There are many limitation of fuel cell from reaching widespread commercial use. ►Nanotechnology can improve the efficiency of fuel cell in several ways. ►By using nanopores you can limit what gets through the membrance. ►Nanoparticles is used to increase the surface area to make the reaction more efficient.
  • 6. ►Carbon nano tube is used to enter the hydrogen into the fuel cell. ►It is an allotropes of carbon with a cylinderical nanostructure. ►The diameter of a nano tube is on the order of a few nano meters. ►It makes the hydrogen storage easier.
  • 7. ►Researches at brown university are developing a catalyst that uses no platinum. The catalyst is made from a sheet of graphene coated with cobalt nanoparticles. ►Researches at cornell university have developed a catalyst using platinum cobalt nanoparticles that produce 12 times more catalytic activity than pure platinum.
  • 8. ►Researchers at the university of copenhagen have demonstrated the ability to significantly reduce the amount of platinum needed as a catalyst in fuel cell by controlling the packing density.
  • 9. ●Approach Nanoparticle Electrolyte: ► Nano-sized electrolyte particles dramatically increase active surface area and hence increases the performance of fuel cell.
  • 10. ● Active catalytic surface area: ► On increasing the catalytic surface area , subsequently it increases the performance of the fuel cell.
  • 11. There are many application of Nano Fuel Cell. Mainly it is classified in three areas: ►Transport ►Portable ►Stationary ◘ Application in Transport 1) The fuel cell bus sector is showing year-on-year growth, with more prototypes being unveiled. 2) Light duty vehicles(LDVs), such as cars and vans. 3) Ferries and smaller boats.
  • 12. ◘ Application in Portable Fuel Cell today defines portable fuel cells as those which are built into, or charge up, products that are designed to be moved. These include military applications (portable soldier power, skid mounted fuel cell generators etc), Auxiliary Power Units (APU) (e.g. for the leisure and trucking industries), portable products (torches, vine trimmers etc).
  • 13. ► It is eco-friendly , noiseless and has no rotating part. ► Wide chioce of fuel for fuel cell. ► Higher efficiency up to 60% as compared to conventional which has 30%. ► Require less space. ► In addition to electric power, fuel cell plant also supply hot water , space heat and stream. ► No transmission and distribution losses.
  • 14. ► Cost to implement a fiel cell system exceeds $ 4000 per KW. ► Lack of Hydrogen Infrastructure. ► Low life time of Fuek cell..
  • 15. ►The NANOTECH REGENERATIVE FUEL CELLS provides solutions for the problems, which are effectively in internal combustion engines. Here, developments in fuel cells are making it useful in ultimate ways. It concludes that our environment and renewable resources will be preserve. It will lead to a new evolution in automobiles. To compress more power into smaller volumes, researchers have begun to build fuel cells on the fuzzy frontier of nanotechnology.
