摘要：

Fuel-cell catalyst layers are made from inks comprised of ionomer, catalyst, and solvent. Ionomer interactions within the ink and how they map to catalyst-layer properties are not well understood. Here we study ink stability over time to elucidate stability windows dictated by solvent dielectric constant. Furthermore, we show how the addition of Nafion affects both the stability and aggregation behavior of the ink.
