In this work, using an in-house made Loschmidt diffusion cell, we measure the effective coefficient of dry gas (O 2 –N 2 ) diffusion in cathode catalyst layers of PEM fuel cells at 25 °C and 1 atmosphere. The thicknesses of the catalyst layers und

Water permeabilities at 70 °C through Nafion membranes, ranging in thickness from 6 to 201 μm, are reported. Three types of water permeation are described: hydraulic permeation (liquid–liquid permeation), pervaporation-like permeation (liquid–v

Mass transport phenomena under reduced RH were studied in H2/O2, air and heliox. IR corrected limiting current density and EIS were employed to identify the predominant transport mechanism at various RHs and current densities. It was found that the l

Aggregation of Nafion in water and in n-propyl alcohol (NPA)/water and its influence on the size of Pt/C agglomerates in catalyst inks has been studied by Dynamic Light Scattering (DLS). DLS shows that Nafion more strongly aggregates in water than in

Understanding the factors that control microstructure formation in catalyst layers (CLs) of polymer electrolyte fuel cells is of vital importance for improving the operation of these cells. Here, we employ, for the first time, coarse-grained molecula

A high-molecular-weight fluorinated poly(aryl ether) with a 4-bromophenyl pendant group has been synthesized based on a bromo-bisphenol. A phosphonic acid derivative is readily prepared from this in high conversion yield. The phosphonated polymer pos
