FUEL-CELL CAR

INTRODUCTION

BASIC PROBLEMS IN AUTOMOBILE INDUSTRY DWINDLING OF PETROLEUM RESOURSES INCREASING STRINGENT STANDARD REGARDING POLLUTANTS

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

FUEL-CELL CONCEPT CHEMICAL ELECTRICAL

TYPES OF ELECTROLYTES THIN MEMBRANE CAUSTIC POTASH PHOSPHORIC ACID MOLTEN CARBONATE SLOID ZIRCON-OXIDE

DEVELOPMENT OF FUEL-CELL CAR FIRST PROTOTYPE FUEL-CELL CAR----1994 IT WAS NAMED AS “NECAR-1” FEATURES:- It was 3.5 tonne, MERCEDES BENZ-180 van Power = 50kW Speed = 90 kmph

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 280Lt of H2

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

HYDROGEN STORAGE ?

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”

METHANOL AS AN IDEAL FUEL Cleaner than gasoline Renewable source of energy When it is reformed at 400-475oc H2 is liberated

NECAR-3 FEATURES:- 3.75m length Power = 50kW Its own H2 on board by reforming methanol 400km on 38Lt of methanol

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%

PEM FUEL-CELL

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

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.
