BASIC PROBLEMS IN AUTOMOBILE INDUSTRY
DWINDLING OF PETROLEUM RESOURSES INCREASING STRINGENT STANDARD REGARDING POLLUTANTS
4
WHY FUEL-CELL CARS ? Better in terms of power dynamic performance and serviceability Lighter and offer a greater range between refueling No harmful emissions Ideally suited to volume built products

DEVELOPMENT OF FUEL-CELL CAR
FIRST PROTOTYPE FUEL-CELL CAR IT WAS NAMED AS “NECAR-1” FEATURES:- It was 3.5 tonne, MERCEDES BENZ-180 van Power = 50kW Speed = 90 kmph
9
2nd PROTOTYPE Multipurpose vehicle Maximum speed = 110 kmph
Named NECAR-2 (1996) FEATURES:- Multipurpose vehicle Maximum speed = 110 kmph Range of 250km using fuel load of Lt of H2
10
NEBUS Zero emission bus Power = 190kW 15% better than diesel engine
FEATURES:- Zero emission bus Power = 190kW 15% better than diesel engine Maximum speed = 80kmph
11
HYDROGEN STORAGE ?
12
REFORMING A HYDROCARBON LIQUID REFORMING IS A PROCESS OF
SOLUTION REFORMING A HYDROCARBON LIQUID REFORMING IS A PROCESS OF “VAPOURSING THE HYDROCARBON LIQUID, THEN INJECTING A MIXTURE OF FUEL VAPOUR, AIR & WATER VAPOUR IN TO A CATALYIC REFORMER”
13
METHANOL AS AN IDEAL FUEL
Cleaner than gasoline Renewable source of energy When it is reformed at oc H2 is liberated
14
NECAR-3 FEATURES:- 3.75m length Power = 50kW
Its own H2 on board by reforming methanol 400km on 38Lt of methanol
15
NECAR-4 (Latest) Uses liquid H2 Fuel is stored in cryogenic cylinder
FEATURES:- Uses liquid H2 Fuel is stored in cryogenic cylinder Power = 5kW Efficiency at wheels = 36%
16
PEM FUEL-CELL
18
FUTURE OF FUEL-CELL CAR
A 3-pronged strategy involving methanol, gasoline and hydrogen options will be perused Cost 10 times as gasoline-powered engine To decrease cost, integration of the system is required
19
FUEL-CELL ALONE OR IN COMBINATION
Powerful fuel-cell is needed COMBINATION WIYH BATTERIES:- The fuel-cells act as battery chargers, while the batteries take the heavy loads and let the fuel-cells operate more smoothly

ADVANTAGES They are lighter than conventional than lead –acid batteries. The fuel cells gives of “NO” harmful emissions. They are ideally suited to volume built products, making for competitive cost. Fuel cells generate electricity by converting oxygen and hydrogen into water without combustion. Fuel cells are quiet, effective and, because they have no movable parts, very dependable. Fuel cells are superior to combustion engines because of their dependability, energy efficiency, and environmental friendliness. A fuel-cell system in a car will be almost maintenance free. They are more at par in terms of power, dynamic performance and serviceability.
