Harnessing Hydrogen for Power:

Hydrogen Cars

What exactly is a Hydrogen Car

In a hydrogen car, its primary source of power is from breaking down hydrogen The use of hydrogen usually happens by two methods

Hydrogen can be burned much like the combustion reaction that takes place in the gas powered cars seen today. This is called a internal hydrogen combustion engine

Hydrogen can be set up to react with oxygen to produce water and electricity. This is called a fuel cell.

Ways of Getting Hydrogen These are the important ways now used :

S.S

BMW’s project for hydrogen car

BMW took the initiative step to create a hydrogen fuel car

IT tested it’s BMW7 first time at aug 7 2015

it accelerated 0-60 in 9.5 sec only

Hydrogen fuel cell:-

It gets hydrogen from hydrogen tank and air from atmosphere.

it generates power by using these two gases

The power can be depends upon no. of individual fuel cells used(0.7v)

Hydrogen tank:-

It is present at the back portion of the car.

It as made up of impact resistant polymer

Power control unit:- It governs the flow of power

Comparable Efficiencies Hydrogen Fuel cells at over 50%

efficiencyFossil fuel powered car at 10% - 20%

efficiencyHybrid powered cars have 30% - 35%

efficiencyEthanol is less efficient than fossil fuel

- ethanol gets 20% less mpg than fossil fuels

AdvantagesZero emissions (pure water is produced)No dependence on foreign oilAbility to harvest solar and renewable

energyNot many moving parts in a vehicle (more

mileage before things start breaking) Hydrogen weighs less than gasoline

(vehicles would not need as much energy to move)

Companies Getting Involved

Ford- P2000

Honda- FCX

BMW - Hydrogen 7

Mazda- Wankel motor

General Motors- Sequel

conclusion

If use this technology we can completely reduce the wastage of fossil fuels. We can also reduce the cost of fuel
