Automobile Fuel Cells:
Fuel Cells operate like the ETC of mitochondria.
1. hydrogen atoms (H2) enter
into a fuel cell and an anode splits it to electron and protons.
Electrons move along a external circuit to power a drive motor.
3. Protons migrate through a membrane toward a cathode.
4. A catalyst combines the electrons and protons with oxygen from the
air generating water and heat. Many membrane cells can be combined
for greater power.
