A fuel cell vehicle (FCV) is a type of electric vehicle that uses a fuel cell to generate electricity. The fuel cell converts hydrogen gas and oxygen from the air into electricity through an electrochemical reaction, with water vapor as the only byproduct. This electricity then powers the vehicle's electric motor. Fuel cell vehicles are known for their quick refueling times and long driving ranges, making them a promising alternative to traditional gasoline-powered cars and battery electric vehicles. They produce zero tailpipe emissions, contributing to reduced air pollution and a lower carbon footprint.
