fuel cells
Hydrogen power sources
Fuel cells are devices that convert chemical energy directly into electricity through an electrochemical reaction, typically combining hydrogen and oxygen to produce power, water, and heat.
Unlike batteries, which store energy, fuel cells generate electricity continuously as long as fuel is supplied.
They power everything from spacecraft and buses to backup generators, offering high efficiency and low emissions.
Hydrogen fuel cells may eventually replace internal combustion engines in vehicles.
