GDL (Gas Diffusion Layer) is a key component for performance and durability of PEMFC (Proton Exchange Membrane Fuel Cell). This porous medium (carbon fibers/grains, hydrophobic treatments…) ensures transfers (electrical, heat, gas, liquid) between active layers and feeding channels.

The aim of this thesis is to improve the understanding on the link between properties of GDL (thickness, structure, uniformity, treatments …) and their performance.

This work will be based on numerous developments in-house and with partners (performance tests of different GDL, characterization of their properties, local modeling, and performance modeling…). It will use/combine/improve these approaches to improve the understanding on the link properties of GDL/transfers/water management/performance. Some specific developments (ex-situ and in-situ characterizations, simulation, manufacturing/test of controlled structures…) will be done as necessary. On this basis, improvements of GDL will be proposed and tested.

This thesis will be done in close collaboration between CEA / LCPEM recognized as a specialist in component development and modeling of Fuel Cells, CNRS/IMFT recognized as a specialist in porous media, and an industrial partner.

This position is open until it is filled.
