Well the Ballard web site has a page on how their "Proton Exchange Membrane
Fuel Cell" (PEM) works.

"The fundamental component of the Ballard fuel cell consists of two
electrodes, the anode and the cathode, separated by a polymer membrane
electrolyte. Each of the electrodes is coated on one side with a thin platinum
catalyst layer."

This electrode assembly makes up one fuel cell plate, which are combined to
create the power unit. The number of plates in a unit determines its power
ouput.
