The Technology Behind Hydrogen Fuel Cell Vehicle - Hydrogen fuel cells utilize an electrochemical process to generate electricity from hydrogen and oxygen. In a fuel cell, hydrogen flows into the anode while oxygen flows into the cathode. A proton-exchange membrane allows protons to pass through to the cathode while blocking electrons. The electrons are forced to travel through an ... https://www.zupyak.com/p/4404852/t/hydrogen-fuel-cell-vehicles-the-future-of-transportation
