•Automotive Engineering has made huge progress towards the production of Green cars and Zero emission vehicles.

Battery-electric vehicles (BEVs) dominate the talk about zero-emission vehicles, and cars like the Chevrolet Bolt EV and Tesla Model 3 are well-known examples of BEV technology. But another type of electric vehicle — the fuel cell electric vehicle (FCEV) — also produces virtually no harmful exhaust emissions and has virtually all of the other advantages of a BEV.

•Furthermore, an FCEV offers quick refueling in a process that mimics filling the gasoline tank of a conventional car. Thus, a fuel cell car regains its full driving range in a matter of five or 10 minutes versus the lengthy charge times of current BEVs.

•FCEVs use a propulsion system similar to that of electric vehicles, where energy stored as hydrogen is converted to electricity by the fuel cell.

•FCEVs are fueled with pure hydrogen gas stored in a tank on the vehicle.

•Similar to conventional internal combustion engine vehicles, they can fuel in less than 4 minutes and have a driving range over 300 miles.

• FCEVs are equipped with other advanced technologies to increase efficiency, such as regenerative braking systems that capture the energy lost during braking and store it in a battery. Major automobile manufacturers are offering a limited but growing number of production FCEVs to the public in certain markets, in sync with what the developing infrastructure can support.
