The article talks about how future cars may run on fuel cells that use hydrogen, which is a clean fuel. These cars could help with concerns about air pollution and climate change. The researchers believe that these cars will become more popular after people get used to advanced internal combustion engine (ICE) and hybrid cars. The focus is on finding new fuels because we worry about running out of oil and want cleaner air. To be successful, future cars need to be technically possible, have the right places to refuel, and be liked by customers. Fuel-cell cars could be a great option for the future, especially in cities, as they are quiet, efficient, and don't need outside hydrogen sources.
