A hydrogen fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen, producing only water as a byproduct.
It is a clean energy technology for vehicles, power generation and portable devices.
Hydrogen enters the anode where it splits into protons and electrons. The electrons flow through an external circuit generating electricity, while protons pass through the electrolyte to the cathode, where they combine with oxygen and electrons to form water.
Proton Exchange Membrane (PEM) fuel cells are popular for vehicles due to fast startup and high efficiency.
