Nanostructure of ionomer in fuel cell catalyst ink by SANS
Zero emission automotive using hydrogen as a fuel and powered by a proton exchange membrane (PEM) fuel cell is now commercially available. However, large-scale commercialization of fuel cell vehicles requires progress in performance, cost and durability, for which the electrode is the most limiting component. It is made of a random assembly of platinum and carbon based nanoparticles within a proton conducting polymer network. The electrode is obtained from a slurry after evaporating the solvents. Currently, research and development to improve the performance and reduce the manufacturing cost rely on a trial and error basis, because information is lacking. Indeed, little is known on the structure of the slurry, especially regarding the ionomer dispersion, whereas it is now established that it plays a crucial role. The proposed experiment aims at using SANS with contrast variation to characterize the ink structure, and more precisely the dispersion of the ionomer, to estimate its degree of agglomeration and its coverage on the catalyst support. Thisis a preliminary study, as a prerequisite for the PhD project that has been funded in the frame of the InnovaXN program.
