Hydrogen Fuel Cell Vehicles (HFCVs) are a type of electric vehicle that uses hydrogen gas to power an electric motor. They generate electricity through a chemical reaction between hydrogen and oxygen in a fuel cell, producing only water vapor as a byproduct. This makes HFCVs an environmentally friendly alternative to traditional gasoline-powered cars. HFCVs are refueled at specialized hydrogen stations, which can fill the vehicle's tank in just a few minutes, similar to conventional refueling. They offer a longer driving range compared to battery electric vehicles, making them a practical option for many drivers looking for sustainable transportation solutions.
