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.

Fluoropolymer ionomers with reduced catalyst poisoning and articles therefrom

Materials are provided that may be useful as ionomers or polymer ionomers, including compounds including bis sulfonyl imide groups which may be highly fluorinated and may be polymers.
