Fuel Cells

Hydrogen fuel cells are electrochemical cells converting the chemical energy of hydrogen into electricity. Hydrogen stores about ten times more energy than lithium-ion battery packs, including the weight of the hydrogen tanks. This is one of the reasons why hydrogen is seen as an enabler for electrification of vehicles that could be challenging to electrify using batteries. Such vehicles are typic
