Abstract
The gas diffusion layer (GDL) plays a key role in the overall
performance/durability of a polymer electrolyte fuel cell (PEFC).
Of profound importance, especially in the context of water
management and flooding phenomena, is the influence of the
underlying pore morphology and wetting characteristics of the
GDL microstructure. In this article, we present the digital
volumetric imaging (DVI) technique in order to generate the 3-D
carbon paper GDL microstructure. The internal pore structure and
the local microstructural variations in terms of fiber alignment and
fiber/binder distributions are investigated using the several 3-D
thin sections of the sample obtained from DVI.
