A Hydrogen Fuel Cell Vehicle (HFCV) is a type of electric vehicle that uses hydrogen gas to power an electric motor. It generates 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 equipped with a hydrogen storage tank, which stores the gas under high pressure. They can be refueled at specialized hydrogen stations in a matter of minutes, similar to refueling a gasoline vehicle. This quick refueling time, along with a longer driving range, makes HFCVs a promising option for sustainable transportation.
