Described herein is a coating composition comprising: (a) a metal catalyst, wherein the metal catalyst comprises at least one of platinum, ruthenium, iridium, and alloys and combinations thereof; (b) an at least highly fluorinated ionomer comprising a polymer backbone and a plurality of first side chains pendant therefrom, wherein the first side chain comprises at least one protogenic group, wherein the protogenic group is selected from a sulfonic acid, a bis(sulfonyl)imide, a sulfonamide, a sulfonyl methide, and salts and combinations thereof, and wherein the polymer backbone comprises an average of at least 14 carbon atoms between adjacent first side chains along the polymer backbone; and (c) a solvent. Such coating compositions may be used to make electrodes for electrochemical cells and have been shown to have reduced poisoning of the catalyst.
