Compression hétérogène de Couche de Diffusion de Gaz dans la Pile à Combustible de type PEMFC

Abstract : In a Proton Exchange Membrane Fuel Cell assembly, the Gas Diffusion Layers are submitted to compression between the fluidic gas circuits. Thus, this highly porous carbon fibre material undergoes heterogeneous finite strains that influence the fuel cell performances and durability. In this work, the effect of pattern size on the material deformation was investigated experimentally, and compared with Finite Element Modeling computed using homogeneous mechanical behavior from the state of the art.
