Dynamic characterization method of Gas Diffusion Layers for high compressive loads
Résumé
In Proton Exchange Membrane Fuel Cells
(PEMFC), Gas Diffusion Layer (GDL) has a major role in
the global system performances. This is the reason why many
research investigations try to model and optimize the GDL
physical properties. Currently, the major drawback of these
models is to obtain representative GDL mechanical and physical
input parameters. In this paper, an experimental method using
Dynamic Mechanical Analysis (DMA) is detailed to properly
obtain the GDL Young’s Modulus (or compression modulus) for
high compressive loads under dynamic excitation.
