An Overview of Hydrogen Fuel Cell EVs
Hydrogen fuel cell electric vehicles may not have caught on like battery electric vehicles (BEVs), but they may still have a future in transport. While BEVs use charged battery packs, hydrogen fuel cell EVs generate electricity through a chemical reaction between hydrogen and oxygen. The only byproducts are water vapor and warm air, making them a zero-emission alternative to gas-powered cars. Instead of a lithium-ion battery pack, hydrogen cars rely on electricity from the hydrogen-oxygen reaction to power their motors. However, hydrogen vehicles still face major hurdles before achieving mass adoption. Toyota is the only automaker to make a notable…
