As a potential candidate for an environmentally benign and a highly efficient
electric power generation technology, proton exchange membrane fuel cells
(PEMFC) are now attracting enormous interest for various applications [1-4]. Gasdiffusion
electrode (GDE) structures in polymer electrolyte fuel cell have evolved
from two layers to three layer structure. Three layer electrodes are made by a
porous support layer (carbon paper), a diffusion layer consisting of carbon particles
and polytetrafluoroethylene (PTFE) and a catalyst layer formed by Pt/C and Nafion.
The performances of the electrodes depend on many parameters one of them is
related to the thickness and morphology of diffusion layer. Diffusion layer have the
role of reactant permeation from flow fields to catalytic sites. Altering the
composition of the diffusion layer can lead to substantial improvements in the
performance of the cell.
