Abstract: A catalyst ink is provided comprising: a) solids, comprising: i) a catalyst material, and ii) a polymer electrolyte; b) an aqueous solvent; and c) a coalescing solvent. In some embodiments, the coalescing solvent is selected from the group consisting of alkanes, alkenes, amines, ethers, and aromatic compounds which may optionally be substituted. In some embodiments, the coalescing solvent is selected from the group consisting of partially fluorinated alkanes, partially fluorinated tertiary amines, fully fluorinated alkanes and fully fluorinated tertiary amines. In another aspect, the present disclosure provides a fuel cell membrane electrode assembly comprising a catalyst layer comprising a coalescing solvent. In another aspect, the present disclosure provides a method of making a fuel cell membrane electrode assembly comprising a step of applying a catalyst ink according to the present disclosure to one or more of: a) a polymer electrolyte membrane, and b) a porous, electrically conductive gas diffusion layer.
