Abstract
An ink composition for forming a fuel cell electrode, and in particular, a fuel cell cathode layer is provided. The ink composition includes a first protogenic group-containing ionomer having an equivalent weight less than 800, an optional second protogenic group-containing ionomer having an equivalent weight greater than 800, and a catalyst composition. Electrode layers formed from the ink composition are also provided.
