2. How They Work:

- Hydrogen is stored in high-pressure tanks and is fed into the fuel cell stack.

- In the fuel cell, hydrogen molecules are split into protons and electrons. Protons move through an electrolyte membrane,

   while electrons create an electric current that powers the motor.

- Oxygen from the air is also introduced to the fuel cell, and together with hydrogen, it creates electricity and water vapor as the by product.

- The electric motor drives the vehicle's wheels, and the only emission is water vapor.

Here's a detailed step-by-step explanation of how Hydrogen Fuel Cell Vehicles (FCVs) works:

Hydrogen Fuel Cell Vehicles (FCVs) represent a promising and environmentally friendly alternative to conventional gasoline and diesel vehicles. These vehicles operate on the principle of electrochemical reactions within fuel cells, which generate electricity to power an electric motor, emitting only water vapor as a by product. Here's a detailed step-by-step explanation of how Hydrogen FCVs work:

1. Hydrogen Fuel Supply:

The process begins with the supply of hydrogen fuel. Hydrogen is typically stored in high-pressure tanks on the vehicle. This hydrogen can be produced through various methods, including steam methane reforming (SMR), electrolysis, or biomass conversion.

2. Hydrogen Storage:

The high-pressure tanks store the gaseous hydrogen. These tanks are designed to withstand high pressures, ensuring safe storage and transportation.

3. Hydrogen Flow to Fuel Cell Stack:

When the driver accelerates, a valve opens to allow the flow of hydrogen from the storage tanks to the Fuel Cell Stack.

4. Fuel Cell Stack:

The heart of an FCV is the Fuel Cell Stack. It consists of multiple individual fuel cells stacked together.

Each fuel cell contains three main components: an anode, a cathode, and an electrolyte membrane (typically made of a polymer).

Hydrogen gas is delivered to the anode side, while oxygen from the air is supplied to the cathode side.

5. Electrochemical Reaction:

Hydrogen molecules (H2) are split into protons (H+) and electrons (e-) at the anode.

Electrons are channeled through an external circuit, creating an electric current. This current powers an electric motor, propelling the vehicle. 

6. Proton Migration:

Protons generated at the anode move through the electrolyte membrane towards the cathode.

7. Oxygen Reaction:

Oxygen molecules (O2) from the air combine with electrons and protons at the cathode to form water (H2O) as a by product.

8. Generation of Electricity:

The movement of protons through the electrolyte membrane creates a flow of positive charges, or electricity.

This electricity powers the vehicle's electric motor, which drives the wheels and propels the FCV forward.

9. Water Vapor Emission:

The only by product of this electrochemical reaction is water vapor, which exits through the tailpipe. This emission is environmentally friendly and contributes to cleaner air.

10. Vehicle Movement:

As long as there is a supply of hydrogen and oxygen, the electrochemical reactions in the Fuel Cell Stack continue, providing a continuous source of electricity to the electric motor.

The driver operates the FCV much like a conventional vehicle, controlling acceleration, braking, and steering.

11. Regenerative Braking (Optional):

Many FCVs incorporate regenerative braking systems. These systems capture and store energy typically lost as heat during braking.

This recovered energy can be used to further power the vehicle, improving overall efficiency.
