Coupling between Adsorption, Structure, and Rheology in Short-Side-Chain PFSA Ionomer/Carbon Black Suspensions in N-Propanol/Water

Abstract The rheological behavior of proton exchange membrane fuel cell catalyst inks arises from the coupled structuring of carbon particles and perfluorosulfonic acid (PFSA) ionomer dispersions, both strongly influenced by solvent composition. Here, the microstructure, ionomer...
