Fuel cell vehicles are similar to electric vehicles except that they get their power from H2. A hydrogen car, also known as a fuel cell vehicle (FCV or FCEV), is not completely unlike a battery electric vehicle (EV or BEV) in a number of ways. Most importantly, they both use an electric motor instead of an internal combustion engine as is the case with vehicles that are powered by gasoline, for instance.
As similar as they may be, there is also a list of substantial differences between the two.
