Step 1 :
- At the cathode, the electrons and positively charged hydrogen ions combine with oxygen to form water, which flows out of the cell.
- At the anode, a platinum catalyst causes the hydrogen to split into positive hydrogen ions (protons) and negatively charged electrons.
- The polymer electrolyte membrane (PEM) allows only the positively charged ions to pass through it to the cathode. The negatively charged electrons creating an electrical current on external circuit.
- Hydrogen fuel is channeled through field flow plates to the anode on one side of the fuel cell, while oxidant (oxygen or air) is channeled to the cathode on the other side of the cell.
