Hydrogen fuel cell vehicles are a new type of clean and quiet cars that work by creating energy through a reaction between hydrogen and oxygen, producing only water as a byproduct. These vehicles aim to reduce pollution and noise caused by traditional cars. They run on hydrogen, which can be made without using fossil fuels. The infrastructure for hydrogen refueling stations is being developed by a collaboration between car manufacturers, governments, and energy companies. Currently, over 180 hydrogen refueling stations are being built, with more planned, as carmakers aim to launch these vehicles soon. This technology is seen as a current and promising option for the future of transportation.
