Hydrogen Fuel Cell Electric Vehicles (FCEVs)

Detailed overview of innovation with sample startups and prominent university research


What it is

Hydrogen Fuel Cell Electric Vehicles (FCEVs) are powered by hydrogen fuel cells that convert hydrogen gas into electricity, providing power to the vehicle’s motor. Unlike BEVs that rely on batteries, FCEVs refuel with hydrogen gas, similar to gasoline-powered vehicles.

Impact on climate action

Hydrogen Fuel Cell Electric Vehicles (FCEVs) offer a transformative shift in electric mobility, reducing carbon emissions and enhancing climate action. With zero tailpipe emissions and efficient hydrogen production methods, FCEVs mitigate air pollution and dependency on fossil fuels, accelerating the transition towards a sustainable transportation infrastructure.

Underlying
Technology

  • Hydrogen Fuel Cells: A fuel cell is an electrochemical device that combines hydrogen and oxygen to produce electricity, heat, and water. The core of a fuel cell is a membrane that allows the passage of hydrogen ions but not electrons, creating an electrical current.
  • Hydrogen Storage and Refueling: Hydrogen gas is stored onboard the vehicle in high-pressure tanks or cryogenic tanks. Refueling an FCEV with hydrogen is a quick process, similar to filling up a gasoline tank.
  • Electric Motor Propulsion: The electricity generated by the fuel cell powers the vehicle’s electric motor, providing the drive force.
  • Emissions: FCEVs emit only water vapor, making them a zero-emission vehicle.
  • Hydrogen Production: The production of hydrogen is a critical aspect of FCEV technology. Ideally, hydrogen should be produced from renewable energy sources like solar, wind, or hydroelectric power to ensure sustainability.
