Electrostatically Limited PFSA Ionomer Adsorption to Catalyst Particles in Catalyst Inks

Abstract Understanding and controlling ionomer adsorption in catalyst inks is critical to optimizing catalyst-layer structure and performance in membrane-electrode assemblies. Here, we systematically quantify perfluorosulfonic-acid (PFSA) ionomer adsorption across a diverse set o...
