  • Modified Stoichiometric Oxygen-Hydrogen (MOH) Gas is the best Hydrogen Storage. It can be produced out of water, by a low-power (0.5Wh/L) ultrasono-modified non-catalyst electrolysis, at a cost, close to zero. MOH Gas can be compressed (100-1,000bar), liquefied (1bar/-178deg.C), filled and stored in CNG/LNG bottles and tanks, cannot be ignited by a spark, does not perform leakage and embrittlement as Hydrogen does, it is 2.5 times DENSER : (167kgH in 1m3MOH vs 70kgH in 1m3H), it is 100 times CHEAPER than the hydrogen ($0.10/kg MOH vs $10/kg H), Pure Hydrogen and Oxygen can be easily extracted out of MOH on-board, on-demand, MOH can be used as a Direct-Injection ICE Fuel as well. fuels.alle.bg

  3. 3. INTRODUCTION  FUEL CELL ARE DEVICES TO CONVERT CHEMICAL ENERGY OF FUEL CELL INTO ELECTRICAL ENERGY WITHOUT USE OF HEAT ENGINE.  IT IS POSSIBLE DUE TO REDOX REACTION.  THE CONVENTIONAL PROCESS TO PRODUCE ELECTRICAL ENERGY CHEMICAL ENRGY HEAT MECHANICAL ENERGY ELECTRICAL ENERGY
  4. 4. HISTORY OF FUEL CELL  1839 SIR WILLLIAM ROBERT GROOVE (GAS VOLTAIC BATTERY (1ST FUEL )  1955 FRANCIS THOMAS BACON (5KW STATIONARY AFC)  1960 GRUBB & NIEDRUCH (PEM FUEL CELL)  1967 GM ELECTROVAN  1969 NASA (FIRST AFC ON MOON)
  5. 5. PRINCIPLE OF FUEL CELL  IT CONSISTS OF ELECTRODE, ELECTROLYTE & CATALYST TO FACILITATE ELECTROCHEMICAL REDOX REACTION.  BASIC ARRANGEMENT IN FUEL CELL CAN BE REPRESENTED AS FOLLOWS:- FUEL ELECTRODE ELECTROLYTE ELECTRODE OXIDANT  ANODE & CATHODE :- THE MATERIAL WHICH HAVE HIGH ELECTRON CONDUCTIVITY & ZERO PROTON CONDUCTIVITY(POROUS CARBON ELECTRODE)  CATALYST :- Pt / Cd  ELECTROLYTE :- HIGH PROTON CONDUCTIVTY & ZERO ELECTRON CONDUCTIVITY (KOH, NAOH)
  6. 6. TYPES OF FUEL CELL
  7. 7. HYDROGEN FUEL CELL SYSTEM  AT ANODE, THE FUEL (HYDOGEN) UNDERGOES OXIDATION & RELEASE ELECTRON.  THESE ELECTRON FLOW THROUGH EXTERNAL CIRCUIT TO CATHODE.  AT CATHODE, OXIDANT(OXYGEN) GET REDUCED.  THE ELECTRON PRODUCE ELECTRICITY WHILE PASSING THROUGH EXTERNAL CIRCUIT.
  8. 8. HYDROGEN FUEL CELL SYSTEM(CONT.)  AT ANODE, H2 4H++ 4e-  AT CATHODE, O2 + 4H+ + 4e- 2H2O  OVERALL REACTION, 2H2 + O2 2H2O
  9. 9. WHY WE CHOOSE HYDROGEN AS A FUEL?  Disperses quickly  Is non-toxic  Produces water upon combustion  Can be stored safely  Does not plume  Does not leach  Is stable in ambient temperatures  The Hydrogen Economy infrastructure is less expensive  The elimination of greenhouse gases  The elimination of economic dependence
  10. 10. HYDROGEN FUEL CELL VEHICLE
  11. 11. EFFICIENCY OF HYDROGEN FUEL CELL VEHICLE  THEORETICAL EFFICIENCY, useful workdone 𝜂 = ∆𝐺 ∆𝐻 ∗ 100 heat of combustion ∆𝐻 FOR HYDROGEN FUEL CELL= -285.5 kj/mol ∆𝐺 FOR HYDROGEN FUEL CELL = -237.39kj/mol 𝜂 = −237.39 −285.5 *100 = 83% BUT ACTUAL EFFICIENCY = 60% - 70%
  12. 12. EMISSION BY HYDROGEN FUEL CELL VEHICLE 0 0.5 1 1.5 2 2.5 Category 1 CO2 EMISSION Series 1 Series 2 0 50 100 150 200 250 300 Category 1 CO EMISSION Series 1 Series 2 0 200 400 600 800 1000 1200 Category 1 NOX EMISSION Series 1 Series 2
  13. 13. COMPARISON B/W HYDROGEN FUEL AND GASOLINE HYDROGEN FUEL  SOURCE IS WATER  SUPPLY IS INFINITE.  RENEWABLE  CARBON FOOTPRINT  COST PER GALLON IS $1.00.  MILES PER GALLON OF HYDROGEN IS 81.  NO ADDITIONAL ENVIRONMENT IMPACT COST. GASOLINE  SOURCE IS CRUDE OIL.  SUPPLY IS FINITE.  NON RENEWABLE.  NO CARBON FOOTPRINT  COST PER GALLON IS $2.23  MILES PER GALLON OF FUEL IS 18-31.  ADDITIONAL ENVIRONMENT IMPACT COST
  14. 14. ADVANTAGE OF FUEL CELL  HIGH EFFICIENCY(70%) AND CLEANER FUEL.  LOW NOISE & LOW THERMAL POLLUTION.  BYPRODUCTS ARE WATER & WASTE HEAT SO NO AIR POLLUTION OCCUR.(NO POLLUTANT)  IT PRODUCE DRINKING WATER OF POTABLE QUALITY.  LOW MAINTENANCE COST AND ECO-FRIENDLY  IT DOES NOT DEPEND ON SIZE RELATIVE TO POWER.  FAST START UP TIME FOR LOW TEMPERATURE.  BOTH LOW POWER DENSITY AND HIGH POWER DENSITY CAN BE POWERED.
  15. 15. DISADVANTAGE OF FUEL CELL  HIGH INITIAL COST.  LIFETIME ARE NOT ACCURATELY KNOWN.  HIGH COST OF PURE HYDROGEN.  IF SINGLE CELL IS DAMAGED, WHOLE STACK SHOULD BE CHECKED.
  16. 16. APPLICATION OF FUEL CELL  THE FIRST COMMERCIAL USE OF FUEL CELL WAS IN NASA SPACE PROGRAM TO GENERATE POWER IN APOLLO IN 1969.  IT IS USED IN VEHICLE INCLUDING AUTOMOBILE, BYCYCLE, AEROPLANE, BOAT, SUB-MARINE.  ALL POPULAR COMPANIES LIKE BMW, MERCEDES, TATA, GM, HONDA, HYUNDAI, FORD, TOYOTA LAUNCHES THEIR FUEL CELL VEHICLE.  USE IN HOUSE FOR POWER BACKUP IN GERMANY, JAPAN AND UK BY “CLEAR EDGE POWER” COMPANY.
  17. 17. FUTURE OF FUEL CELL  FUEL CELL COMMERCIALISATION “STARTED IN 2007”.  IT REPLACES CARBURETOR AND FUEL INJECTION SYSTEM.  PORTABLE FUEL CELL MARKET TO $2.3 BILLION BY 2016. (SOURCE :- RESEARCH AT WWW.GREENCARCONGRESS.COM)  THERE ARE 85 HDROGEN REFUELING STATION IN US IN 2010 WHILE CALIFORNIA HAD 23 IN 2013.  HONDA ANNOUNCED PLAN TO OPEN FIRST FUEL STATION THAT GENERATE HYDROGEN FROM SOLAR POWERED RENEWABLE ELECTROLYSIS.  THE U.S. GOVERNMENT HAS BEEN INVOLVED IN FUEL CELL AND HYDROGEN RESEARCH FOR DECADES NOW.
