The purpose of this paper is to examine the role that water plays in the Polymer (or Proton) Electrolyte Membrane Fuel Cells (PEMFCs -- also called PEFCs). Since proton conduction is the main ionic charge carrier, it is worthwhile to examine how this happens and how the water interacts with the perfluoro-polymer structures; examining the microstructure of the membranes and how they have been modified to overcome the water transport limitations inherent in the PEMFC.
