Fuel Cell Vehicles (FCVs) are a type of electric vehicle that uses a fuel cell to convert hydrogen into electricity, powering an electric motor. This technology offers a clean alternative to traditional gasoline-powered cars, emitting only water vapor as a byproduct. FCVs are gaining popularity due to their potential for reducing greenhouse gas emissions and reliance on fossil fuels. The fuel cell system in these vehicles operates by combining hydrogen stored in tanks with oxygen from the air. This process generates electricity, which drives the vehicle, providing a longer range and quicker refueling times compared to battery electric vehicles. As infrastructure for hydrogen refueling expands, FCVs are poised to play a significant role in the future of sustainable transportation.
