Graphite Plates

Description:

Attached to the electrode backings of a fuel cell stack on either side are large graphite plates. These plates serve a double purpose. One purpose is to act as a conductor by receiving the energy from the electrodes. Its other purpose is to guide the flow of the hydrogen and oxygen through their respective ends of the stack, making sure that the maximum amount of the gasses and moisture comes in contact with the membrane. To prevent gasses from leaking out through the normally porous graphite, the plates are constructed using a much longer and more complex process that creates nonporous plates.
