How Things Work: The Hydrogen Fuel Cell

A fuel cell is a device that uses an electrochemical reaction to generate electricity. A hydrogen fuel cell consists of an anode, a cathode, an electrolyte membrane, and hydrogen as fuel. Hydrogen molecules are striped of their electrons and positively charged from the anode. The protons pass through the “proton exchange membrane” electrolyte whereas the electrons pass through an external circuit (electricity). The waste of the cell is water and carbon dioxide as air is funneled in to react with the H2 atoms.
