Harnessing Chemical Reactions: Hydrogen Cars
Hydrogen cars, also known as fuel cell electric vehicles (FCEVs), work by harnessing the power generated from chemical reactions between hydrogen and oxygen. These vehicles utilize a fuel cell, which is a device that converts hydrogen gas and oxygen from the air into electricity. The main components of a hydrogen car include the fuel cell stack, hydrogen fuel storage tank, and electric motor.
Hydrogen Car: From Storage to Fuel
In a hydrogen car, the process begins with hydrogen being stored in high-pressure tanks or in a liquid state at extremely low temperatures. When the vehicle is in motion, the pressurized hydrogen is released from the tank and enters the fuel cell stack. The fuel cell stack contains layers of individual fuel cells, typically made of a material called proton exchange membrane (PEM) or solid oxide.
Electrochemical reaction powers vehicle with efficiency
Inside each fuel cell, the hydrogen molecules are separated into protons and electrons. The protons pass through the membrane, while the electrons are directed through an external circuit, generating an electric current. The electrons then recombine with the protons, as well as with oxygen from the air in the fuel cell, to produce water vapor as the only byproduct. This electrochemical reaction produces the power needed to run the vehicle.
Efficient Hydrogen Cars Offer Silent Drive
The generated electricity is then used to power an electric motor, which drives the wheels of the car. Since the electric motor has no moving parts, it provides a smooth and silent driving experience. Additionally, hydrogen cars have the advantage of being able to store more energy compared to conventional batteries and can be refueled quickly, similar to traditional gasoline vehicles.
