Influence of the solvent and ionomer types on the fuel cell electrode structure and its water uptake
Proton exchange membrane fuel cell (PEMFC) is a conversion devices that uses the chemical energy of the dioxygen and dihydrogen to produce electricity, heat, with water as a by-product. The main component of the individual cells composing the PEMFC is the Membrane Electrode Assembly (MEA) that is made of a proton conducting polymer electrolyte membrane sandwiched between two electrodes. The electrodes are key and critical components in PEMFC, in terms of cost, performance and durability, as they are the places of the electrochemical reactions. The electrodes are made of platinum (Pt) nanoparticles (~3 nm) supported on electrically conductive mesoporous (high surface area) carbon particles (~40 nm) which are bound in a proton conducting polymer, the ionomer. The proposed experiment aims at systematically investigating the effect of solvent, catalyst and ionomer types on the electrode nanostructure and more precisely on the distribution and swelling behaviour of the ionomer in the electrode with SANS. This will help for a better understanding of the influence of the fabrication process on the structure and dispersion of the ionomer in the electrode, and finally on the performance.
