Hydrogen vehicles are automobiles that use hydrogen as a fuel source to power an electric motor. They typically operate using a fuel cell, which converts hydrogen gas into electricity, emitting only water vapor as a byproduct. This makes them an environmentally friendly alternative to traditional gasoline-powered cars. These vehicles can be refueled quickly, similar to conventional cars, and have a longer driving range compared to battery electric vehicles. Major manufacturers, including Toyota and Honda, have developed hydrogen models, contributing to the growing interest in sustainable transportation solutions.
