Ideal Shift from Gasoline to Hydrogen Fuel Cells

by Alexander Flores

The main alterative for gasoline fuel and battery electric vehicles is one involving the utilization of hydrogen fuel cells. Just how do these hydrogen fuel cells work? Essentially, each fuel cell is an anode and cathode with a proton exchange membrane sandwiched in between. Hydrogen from an onboard tank would enter the anode side of the fuel cell, while oxygen in the atmosphere would enter the cathode side. Once the hydrogen molecule encounters the membrane, a catalyst forces its split into proton and electron. The proton would then move through the fuel cell stack as the electron follows an external circuit, delivering an electric current to the motor and other parts of the vehicle. The proton and electron would join again at the cathode side and combine with oxygen to form water as the main emission. This fascinating science and technological application has many automakers relieved since sales of electric cars and plug-in hybrids are slow. Continue reading
