Hydrogen fuel cell

The hydrogen fuel cell is a fuel cell that uses hydrogen stored in a pressurised tank and oxygen from the surrounding air. It operates by means of the controlled electrochemical combustion of dihydrogen and dioxygen, simultaneously producing electricity, water and heat. When it comes to automobiles, a hydrogen fuel cell can be used to power a buffer battery that drives one or several electric motor(s) to propel the vehicle along. The environmental and technical challenges raised by the distribution and storage of hydrogen remain to be resolved, before hydrogen fuel cells can be relied on as an energy supplement to the lithium-ion batteries in electric vehicles.
