What is a hydrogen car?

Hydrogen cars run on hydrogen fuel which is tapped after hydrogen atoms are broken up and then re-combined with the atoms of oxygen. This can be done through electrolysis, wherein electric current is applied through water. Most of these hydrogen-fueled vehicles operate on fuel cells. There are other hydrogen-based vehicles that however use the traditional internal combustion device through harnessing of liquid hydrogen in place of gasoline.

There are 100% hydrogen powered vehicles that are being used in certain areas around the globe. The downside with these hydrogen vehicles, however, is the lack of infrastructure that would complement the maintenance of these vehicles. It would take trillions of dollars to replace the current gasoline fueling system that most countries use. Also, hydrogen fuel cells that are necessary in harnessing the mechanical energy of hydrogen atoms are quite costly to produce. These devices are also fragile, and they cannot withstand the vibrations and bumps that cars experience during road trips.
