1. FUEL CELL Electric vehicle Prepared by : HidhunLal.T Reg NO: 2201040080 ELECTRONICS ENGINEERING

2. Introduction 01 History 02 BEV & FUEL CELL EV 03 FHEL CELL & WORKING 04 CONTENT

3. FUEL CELL VEHICLE & COMPONENTS LAYOUT 5 ADVANTAGES & DISADVANTAGES 6 CONCLUSION 7 CONTENT

4. Introduction FUEL CELL ARE DEVICES TO CONVERT CHEMICAL ENERGY OF FUEL CELL INTO ELECTRICAL ENERGY Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine They only emit water vapor and warm air.

5. HISTORY 1839 Sir William Robert Grove (GAS VOLTAIC BATTERY (1ST FUEL) 1955 FRANCIS THOMAS BAGON (5KW STATIONARY AFC) 1960 GRUBB (PEM FUEL CELL)) 2021 Toyota Mirai 1969 NASA (FIRST AFC ON MOON) 1967 GM ELECTROVAN

6. BEV & FCEV Battery electric vehicles Fuel cell vehicle Run with the help of electric Motor and Battery Uses Renewal energy sources
And emit less emission Run by electric Motor and Battery
Use existing infrastructure for recharging
long time use Emit less emission than BEV

7. PRINCIPLE OF FUEL CELL 1 IT CONSISTS OF ELECTRODE, ELECTROLYTE & CATALYST 2 BASIC ARRANGEMENT IN FUEL CELL CAN BE REPRESENTED AS FOLLOWS: ANODE > CATALYST> ELECTROLYTE> CATHODE

8. HYDROGEN FUEL CELL SYSTEM 1 IT CONSISTS OF ELECTRODE, ELECTROLYTE & CATALYST TO FACILITATE ELECTROCHEMICAL REDOX REACTION. 2 THESE ELECTRON FLOW THROUGH EXTERNAL CIRCUIT TO CATHODE 3 AT CATHODE, OXIDANT(OXYGEN) GET REDUCED. 4 THE ELECTRON PRODUCE ELECTRICITY WHILE PASSING THROUGH EXTERNAL CIRCUIT.

9. WHY CHOOSE HYDROGEN FUEL Disperses quickly
Is non-toxic
Produces water upon combustion
Does not plum
It is lighter than air (unlike petrol which ‘pools’)
Does not leach
Is stable in ambient temperatures The Hydrogen
The elimination of greenhouse gases

10. Fuel cell vehicle

11. Layout

12. How it works

13. COMPONENTS Battery ( auxiliary) Battery pack DC/DC converter Electric traction motor Fu el cell stack Fu el tank Power electronic control Thermal system

14. Battery pack 2.Battery (auxiliary) 1 . Stores energy generated from regenerative braking

15. DC/DC converter This device converts higher-voltage DC power from the traction battery pack to the lower-voltage DC power needed to run vehicle accessories and recharge the auxiliary battery. And lower voltage DC/DC converter

16. Electric traction motor (FCEV) Tusing power from the fuel cell and the traction battery pack, this motor drives the vehicle’s wheels. Some vehicles use motor generators that perform both the drive and regeneration functions. 1.Electric traction motor (FCEV) Which convert breaking energy kinetic energy to back electrical energy and store in battery which result in 10% extra mileage 2. Regenerating breaking

17. Brushless dc motor . High power-to-weight ratio high speed .good control of Speed Advantages

18. Fuel tank (hydrogen) Stores hydrogen gas onboard the vehicle until it’s needed by the fuel cell. Carbon fiber Inner polymer shell Outer shell Fuel tank (hydrogen)

19. Power electronics controller (FCEV)

20. Powerer electronics controller (EV)

21. ADVANTAGES OF FCEV Less Greenhouse Gas Emissions Less Air Pollutants Reduced Oil Dependence Robust Reliability Improved Efficiency Lower Operational Costs

22. Expensive infrastructure Expensive Less efficient than ev DISADVANTAGES infrastructure Efficiency & safety

23. BEV & FCE IC ENGINE . Which burn fuel inside the engine and produce power Less efficient pollution Maintenance Zero emissions Efficient Less maintenance . Which use battery or fuel cell to power vehicle
