With all the press recently around Battery Electric Vehicles (BEVs), one technology that has perhaps been overlooked is fuel cells. Vehicles powered by hydrogen fuel cells are actually a type of electric vehicle. Instead of carrying around a lot of heavy batteries to draw electricity from, it creates its own electricity from a chemical reaction. This article provides a good overview of the technology. Major automobile manufacturers are still investing in fuel cell technology, such as Mercedes Benz, Hyundai, and GM.

While vehicle powered by fuel cells won’t be mass produced for a number of years, and there are still a number of significant barriers to overcome, they have the potential to become a very attractive alternative fuel vehicle.
