| Abstract: | Polymer electrolyte fuel cells (PEFCs) employ membrane electrolytes for proton transport during the cell reaction. The membrane
forms a key component of the PEFC and its performance is controlled by several physical parameters, viz. water up-take, ion-exchange
capacity, proton conductivity and humidity. The article presents an overview on Nafion membranes highlighting their merits
and demerits with efforts on modified-Nafion membranes.
Energy security refers to various security measures that a given nation, or the global community as a whole, must carryout
to maintain an adequate energy supply |
