Hydrogen, used in the fuel cells of electric vehicles, is the most abundant element in the universe. Although a fuel cell automobile uses electricity, it operates differently than a battery-powered or plug-in hybrid vehicle. In a hydrogen fuel cell vehicle, hydrogen reacts electrochemically to generate electricity, which powers the car.

How do Hydrogen Fuel Cell Vehicles Work?

Hydrogen fuel cell vehicles run on compressed hydrogen petrol, fed into an onboard fuel cell stack that converts the fuel’s chemical energy into electrical energy rather than burning it. This electricity then drives the vehicle’s electric motors. Tailpipe emissions are zero, and the only waste produced is clean water. The fuel cell is made similarly to a battery. Hydrogen enters the anode and comes into touch with a catalyst, which promotes the separation of hydrogen atoms into electrons and protons. The electrons are collected by the conductive current collector, which is linked to the car’s high-voltage circuitry and powers the onboard battery and the motors that spin the wheels.

  • Fuel Cell Stack – A collection of fuel cells that mix oxygen and hydrogen to generate energy and power an electric motor.
  • Fuel Tank – Hydrogen gas is kept in carbon-fibre reinforced tanks to fuel the fuel cell stack.
  • Electric Motor – Powers the car with energy produced in the fuel cell stack.
  • Battery – Captures energy from regenerative braking and adds power to the electric motor.
  • Exhaust – Water vapour, a byproduct of the reaction occurring in the fuel cell stack, is expelled through the exhaust.


Hydrogen fuel cell vehicles are silent, highly energy efficient, emit no pollutants, and have comparable range and performance to gasoline vehicles. Drivers see range, refuelling time, emissions, power, and performance as essential car qualities.


Fuel cell automobiles can carry enough hydrogen fuel for 300-400 miles of driving range, and their tanks can be recharged as quickly as a regular car’s petrol tank. Current lease agreements frequently feature up to three years of complimentary fuel. At the pump, hydrogen costs far more than petrol; nevertheless, a fuel cell car drives approximately twice as far as a regular automobile on the same quantity of fuel.

Rebates and Incentives

California’s Clean Vehicle Rebate Project offers a $4,500 rebate ($7,500 for those meeting income qualifications) to purchasers of fuel cell cars. Additionally, these vehicles are eligible for the Clean Air Vehicle decal, allowing solo access to carpool lanes. Various initiatives are also in place to encourage ownership of clean transportation in low-income and disadvantaged communities.

Benefits of Hydrogen Fuel Cell Vehicle

  • It’s fun to drive.
  • Instant torque and reliable power
  • High-tech, low-maintenance
  • Zero emissions
  • Fast refuelling (3-5 min)
  • High range.
  • Access to carpool lanes, among other incentives
  • Attractive lease pricing is often paired with free fuel and maintenance.

In conclusion, hydrogen fuel cell vehicles are a promising option for sustainable mobility, with significant environmental benefits and the potential for energy independence. With zero exhaust emissions and the ability to refill quickly, they address substantial concerns about air pollution and climate change while providing a practical alternative for long-distance travel. However, infrastructure development and cost remain barriers to broader use. Nonetheless, continuous research and investment in hydrogen fuel cell technology point to a bright future in which these vehicles could significantly define a cleaner, greener transportation scene. As developments continue and challenges are overcome, hydrogen fuel cell vehicles have the potential to revolutionise the way we travel, providing a cleaner, more eco-friendly alternative to traditional internal combustion engine vehicles.
