Hydrogen Fuel Cell

What happens on the anode side? hydrogen diffuses and dissociates into protons and electrons
What happens to the hydrogen proton? to go the cathode
What happen to the hydrogen electron? forced to travel in an external circuit
What is happening on the cathode side? oxygen molecules react with the electrons (which have traveled through the external circuit) and protons to form water.
What is the waste product? water vapor
First: What happens? hydrogen fuel goes to the anode. Oxygen from air go to the cathode
Second: What happens? at the anode, hydrogen splits into positive hydrogen ions (protons) and negatively charged electrons
Third: What happens? the membrane allows only the positively charged ions to pass through it to the cathode. The negatively charged electrons must travel along an external circuit in the cathode, creating an electrical current
Fourth: What happens? at the cathode, the electrons and positively charged hydrogen ions combine with oxygen to form water.
