hydrogen car
Water-vapor exhaust automobile
A hydrogen car is a vehicle powered by hydrogen fuel, typically through a fuel cell that converts hydrogen to electricity.
Unlike battery electric vehicles, hydrogen cars can be refueled in minutes rather than hours: Toyota and Hyundai both make hydrogen cars, but finding a fueling station remains difficult.
The technology promises zero emissions—only water vapor exits the tailpipe—but limited infrastructure has slowed adoption.
