Hydrogen

Fuel cells generate electricity from an electrochemical reaction in which oxygen (air) and a fuel (e.g. hydrogen) combine to form water.

 

This figure shows a cross-section view of a PEM membrane. The figure illustrates the production of electricity, hydrogen and(red) and oxygen(blue). The oxygen and hydrogen molecules enter the cell on different sides, the hydrogen molecules sending electrons around a conductor. The molecule them recombine into water.
This figure shows a cross-section view of a fuel cell.
This is a picture of an actual fuel cell. It was used in the car experiments, located in Applications. The construction of this fuel cell is shown in the cross-section.
