Mesoscopic modeling of ion exchange membranes for energy conversion applications

Status
open
Location

The proposed PhD is taking place in the general context of the development of hydrogen-powered electric vehicles and more specifically aims to improve the tools for modelling and characterizing polymer membranes used in Proton Exchange Membrane Fuel Cells (PEMFC). In this fuel cell technology, in addition to the anode and the cathode, which are the sites of the oxidation of hydrogen and the reduction of oxygen respectively, there is a solid electrolyte made up of a cation-conducting polymer which transfers hydrated protons between the two compartments of the cell. PEM are also used in the case of water electrolysis. The objective of the PhD is to develop molecular simulation approaches to better characterize the properties of this polymer membrane. This involves better identifying the link between the structure of solid polymer electrolytes (topology, crosslinking, swelling, etc.) and the diffusion paths. The proposed work will focus more specifically on perfluorosulfonated membranes. These membranes will be modelled on the mesoscopic scale using Dissipative Particle Dynamics (DPD) simulations.

Keywords: Proton exchange membrane, Fuel Cells, Dissipative Particle Dynamics (DPD)
