Answer:
Fuel cell vehicles use hydrogen gas as a fuel.
Step-by-step explanation:
Hydrogen fuel cell cars use this gas to power the electric motor. Hydrogen and oxygen are combined to generate electricity.
The fuel cell has a low environmental impact, with no vibrations, no noise, no combustion and, even, no emission of particulate matter. Hydrogen provides the most interesting currents, so it is the most common. However, there are other fuels that are being studied.
The by-product of converting hydrogen to electricity is water and heat, which is great for the environment. However, the problem may be precisely in obtaining hydrogen. One of the most polluting sources of hydrogen is natural gas, which can lead to the emission of greenhouse gases. Even so, the first hydrogen fuel cell vehicles can reduce their emissions by more than 30%.
Automobiles powered by hydrogen fuel cells are fueled in a similar way to conventional fuel. Pressurized hydrogen can be found at filling stations and takes less than 10 minutes to "fill the tank".
